Are you a believer in the one true Creator God philosophically, but are having trouble affirming that the world and the universe came from God's will (and it was good) and that logically He exists? Don't forget to pray about the trouble you are having. God will help you along; God wants you to believe that He exists, and so He will hurry to meet you when you get near "home"... This is neither about intelligent design nor against the theories of evolution that are developed by observation of existing life, but it is indicating that God exists and that logically God did start life: see how it goes, read on. Logically life did not just come from nothing, but it is proposed that it came from God...

[edit] Steps

Nothing created everything?

Look for the life in a vacuum, in an empty expanse, and so look for life where it has no cause and no plan. Would you expect it there? No probability at all?
Calculate the chance... If the universe was created by chance (no intelligence), what power does chance have? Chance has no creative ability, since it is just a word; probability has no power; it is merely a number like: a 50, 50 chance of success (either it happened or it did not).
Bet your soul on 50% -- just believe that nothing created everything -- really? Do you feel that lucky? So did mother nature get so lucky that she created life without a plan, without sterile conditions and with no existing organic materials?
Examine the idea of an illusion; if it is an illusion to us - who created the illusion? Where is the illusion coming from or going? Why is there an illusion in the first place?
Diagram of a Typical Animal Cell (called eukaryotic - having nuclei and organelles) Subcellular Components (differ from plant cell and virus). Organelles: (1) nucleolus (2) nucleus (3) ribosome (4) vesicle (5) rough endoplasmic reticulum (ER) (6) Golgi apparatus (7) Cytoskeleton (8) smooth endoplasmic reticulum (9) mitochondria (10) vacuole (11) cytoplasm (12) lysosome (13) centrioles within centrosome [1]

Remember that life produces life. Life comes from life. That is all we know: scientifically it has not been proven beyond a doubt how cells began. No, DNA and RNA couldn't make it very far with no cell in which to operate, no organelles, no nucleus, no food, no biological energy, no organization? Having no place or way for life to begin is as good as saying it could not reasonably happen...

Explosion in a puddle

See the logic, "If the universe created itself, how did something come from nothing?" Even scientists say that the expanding universe is not eternal. It has not existed forever. There was a starting point and before that there was a chunk of matter? So if the universe wasn't there before, how did that chunk of matter come to be -- just "POOF" and it appeared by God's will?
Poof! and "Oh, it was just there." makes no sense at all. So what if DNA took millions of years to develop, then it still needed an enclosed environ (a cell) and organelles (cell parts)... But if there is a God - an all powerful God would have the power to create something out of nothing, not because of any preconceived or preeminent matter, but because the all powerful God can do that by definition!
Put a "lightening rod" in a puddle: could an electrical blast of lightening like an explosion in a puddle cause "purposeless" living cells that would then automatically achieve "genetic programming of uniqueness" and instincts, immune system, healing of injuries, digestion...
Membrane structures. Top: an archaeal phospholipid, 1 isoprene sidechain, 2 ether linkage, 3 L-glycerol, 4 phosphate moieties. Middle: an bacterial and eukaryotic phospholipid: 5 fatty acid, 6 ester linkage, 7 D-glycerol, 8 phosphate moieties. Bottom: 9 lipid bilayer of bacteria and eukaryotes, 10 lipid monolayer of some archaea.[2]

Explain the membrane of the single cell eukaryotes. Plant cell structure is not a simple matter!

1.) Eukaryotes are all cellular organisms including animal, plants, fungi -- and protists (slime molds and protozoans) -- whose cells are organized into complex structures inside of selective semipermeable membranes.

2.) Where did the semipermeable, cytoplasmic membrane (the skin of a cell) and its fluid serum and its first foods come from? Cannibalism -- of... well so that's your answer? Where did that cannibal find enough life to cannibalize?
- Veggies (plant-life) and proteins were the baby food of the first cell? Oh, so how and why were these plants and proteins available? So then the veggies have complex cell structure and would need organic materials in plant energy production from the very first second...
- One typical cell of a plant -- click the number at the left to go to a strictly scientific biology article of Plant Cell Structure...
  
  Wasn't life much too complex for mother nature to solve a million crucial balanced systems! So she did all of that without a brain or any observable form of intelligence?
  
  Plant Cell Structure Photo Image: If millions (or billions) of years of storms in junk yards could never create a modern computer or a beautiful machine of any kind, then what logic says that chaos can create amazing life like one typical cell of a plant and bring it to an excellent, complex status -- well beyond a virus or simple "germ of life."[3]

Nature creates by destroying

Examine exploding volcanoes and colliding of continents, folding and breaking... You know that natures greatest building projects like mountains are created by destructive power.
Look at how nature breaks down things and think about whether creation of life seems natural! Nature is about breaking down rocks to pebbles and to sand, dissolving, oxidizing, mineral deposits, poison, corrosion, erosion, and rot.
Cell Organization 1) Organelle - organlike parts 2) Chloroplast - photosynthesis in plants 3) Cilia - hairlike 4) Cytoplasm - fluid
5) Cytoskeleton - skeletal protein
6) Ribosome - makes protein
7) Endoplasmic reticulum - makes protein 8) Flagella - taillike structure
9) Endomembrane - covering of organelles 10) Golgi apparatus - glycoproteins 11) Lipid-protein specific barriers 12) Lipid bilayer - base membrane 13) Vesicle - internal sac 14) Mitochondrion - makes energy 15 Nucleus/Nucleoid - DNA; Cell_biology

Point out that the most basic "natural" scientific processes called entropy and chaos do not normally improve things: so how did Cell Molecular Organization of life just "happen" (Please see the image with a chart.)?

1. Entropy is disorder or uncertainty in a system and much like inertia it is neutral and only exists because of outside forces. Entropy merely resolves to equilibrium.

2. Equilibrium apparently has no creative powers, and so entropy could do nothing but come to a balanced or settled condition.
Examine the creativity of great explosions, like bombs.... How much creativity is in that? Now visualize the big bang. Massive force so great it's not over yet? The universe is said to still be expanding from that explosion...
- If all life came into existence as the result of "a" big bang -- where did that big bang come from. So how many "big bangs" are there out there? How do you know?
- Obviously there is something much bigger than our known "expanding universe".

Discuss

Discuss that human brains work with much more than just intellect and logic and that when things go beyond our capability to understand then having faith in something larger than natural processes can bring extreme peace. Maybe it's not the answer, but it is peace, and peace in itself is a huge reward, a great return for faith..
Make a never ending list: inspiration, intuition, dread, hope, fear, faith, industriousness, procrastination, calmness, anxiety, anger, ambition, initiative, enthusiasm, boredom, fatigue, illness, health,... family, friendship, trust, honesty...
- To know "everything" is impossible but being a functioning human and striving further to "know" more... Priceless!
- Discuss how self-awareness, self-development and personality all point to highly organized and purposeful traits -- not randomness in our mental processes.
Talk about existence of anything. Express as best you can the amazing intricacy of life and complexity of human "intelligence." Notably, the the virus is unlike the single cell eukaryotes in having not a membrane but a crystalline-related protein coat.

  Bacteria Structure
  
  Talk about the thousands of "precisely" balanced and perfectly regulated biochemical and electrical systems in the simple single cell life.[4]
- How could chaos or entropy create precision, perfect sight, hearing, unfathomable depths of nerves and multiple intelligences plus gender, various amazing species (lightening bugs, electric eels, blind bats with sonar, worms and starfish that can regrow body parts...), racial and familial characteristics?

[edit] Tips

Research more in depth so you can support your answer. People will ridicule you for "blind faith." However, God wants us to know how to believe in Him. We need proof to back ourselves up!
Don't be afraid! Also, live out your faith. If you are being a "poser" believer, and drinking, swearing, gossiping, wearing revealing clothes- people won't respect you.
Pray for guidance from God. He'll know how to put the right words into your mouth.

[edit] Warnings

You will be persecuted. The Bible promises that much. Just pray, and know, and believe, and love. God will pull you through. He has already forgiven us - just be a great witness for Him! Don't be afraid!
Don't overdo pressing the issue with others. Faith is not so much personal as is determined by ones faith; what works with God will usually work for you and others.
1. "God does not respect one person or certain days one above another."
2. "Biblical prophecy is not for personal interpretation (not for just you)."
Yes, you can win a person to a commitment to the existence of God logically.
1. If you couldn't, what would be the point of preaching/teaching.
2. The one taught must determine whether to have "faith" or not. As the spirit and mind are free will agents.
Realize that there are understandings that "prove" God to the willing believer. The existence of "God" is taken by faith.
1. The Great Commission spoken is "Go into all the World and teach the Gospel to all."
2. It was said, "I teach by all means that by some means I may reach some!"
3. If you bury your talents and abilities, then at the End-Time you may expect to hear, "Depart from me you workers of iniquity, for I never knew you."
You cannot over-sway a determination to disbelieve. God and the Word must make sense if they have heard it presented clearly -- and the Holy Spirit must seem real -- so that you may win an "atheist" to become a believer in God (as a Christian).
Do not fail to prove for yourself the most important questions of life -- if God is real:

"What would you do to gain the world? Or, what would you exchange for your soul?"
Do not become over offended when people disagree with you, anyone can be wrong, even you.
Recognize the revelation of God to all mankind: "For the invisible things of him since the creation of the world are clearly seen, being perceived through the things that are made, even his everlasting power and divinity; that they may be without excuse:"(Romans 1:20)
The Holy Spirit has gone throughout the earth and so there is no excuse; now accept God's grace and extend it to others as much as possible: "You are therefore without excuse [for not forgiving], oh man, whoever you are who sit in judgment upon others. For when you pass judgment on your fellow man, you condemn yourself; for you who sit in judgment upon others are guilty of the same misdeeds [repent and let God Judge];"(Romans 2:1)
