The difference is that those who believe in evolution are always looking for evidence to prove the theory and fill in the blanks. Meanwhile, those that believe in creation believe that they know the answer and that there is no need to continue the research. Since the existence of a god (or gods) can't be proven, it's illogical to state one side or the other as irrefutable fact. That said, I still prefer the course of action that results in a greater understanding of our environment and interrelationships between the creatures that have walked the face of the earth over the various interpretations of people who claim to have heard the voice of god. Most people who claim to talk to god now are locked up for their own safety, or hold an elective office. Two thousand years ago, they were called prophets.
Proving the existence of God really depends on what burden of proof you subject your analysis to. If you say, "I will believe in God if he puts 10,000lbs of gold in my driveway tonight but will refuse to believe in Him if He doesn't", then I would suggest you really don't want to know the answer. Likewise, if you say you will only believe in God if He comes down from heaven or if He unmistakably presents Himself to you face to face here and now, then I would say your burden of proof is too high. Why should the God who created you be subject to you and your wishes more than you being subjected to Him? It is illogical for God to capitulate to us on these kinds of tests of faith because we are accountable to Him not the other way around. He sets the rules, not us.
However, if you have an open mind and follow the truth wherever that truth leads you without bias or prejudice, then I am certain you will come to believe that the only valid answer to all of these questions is that there is not only a Creator, but that He alone could have authored Scripture since He alone knows the end from the beginning.
To believe in theistic origins of the universe or in the stochastic biogenesis of life, then you are really believing in and relying on more miracles than someone who professes faith in God. In other words you have to believe thing like:
1) The First Law of Thermodynamics (Conservation of matter and energy) could have been violated for life to appear
2) The Second Law of Thermodynamics (Entropy) could have been violated for life to appear
3) That DNA could have been produced originally without the existence of proteins or that proteins could have originally existed without the DNA that produces them today (real chicken and egg conundrum here)
4) That the coded information sequence contained in DNA was somehow developed before the DNA of that very first spontaneously generated life form. What is the origin of information and how could information pre-populate DNA molecules?
5) That spontaneously generated life forms would have the ability to take in oxygen and nutrients from the outside world, have a system for eliminating poisonous waste back into the outside world, and also have the ability and expertise to replicate/reproduce itself before it died. All of these complex systems would have to have been simultaneously in operation in that first life form or it would never have survived pas the first generation.
6) That extremely small and rather irrational probabilities such as 1:40,000th power (a number with 40,000 zeros after it) or even much more unlikely probabilities happening on a very routine basis (winning the lottery every week for the rest of your life would be a much more probable outcome than what science relies on with evolutionary theory) in order for simple and then complex life to have formed
7) That the earth that has more than a 100 perfectly balanced factors which are required for life and all interact with one another accidentally came together (nuclear forces, the size and distance of the earth from the sun, the surface gravity of the earth, rotational period of the earth the axial tilt of the earth, the thickness of the ozone layer, and many, many other factors). A small percentage change in any of these and life would not be possible here on the third rock from the sun.
Well, there are thousands of other "miracles" which would have to have occurred in the right sequence and without negatively affecting all of the other factors if the atheistic propositions on the origins of the universe and life on this planet are to be believed. Its not like science denies all of these established facts, rather they prefer that people believe in absurd probabilities and in violations of natural law in order for their tale of "there is no God" to be believed. The choice is really yours to make.
