That molecules ended up hitting each other forming amino acids and biological matter and that by chance Earth just had just the right properties to help harbor life, and that these molecules turned into living things, and eventually just knew how to evolve into more complex sentient beings, like all this happened by mere accident.
There is plenty of evidence that simple chemicals spontaneously form more complicated bonds.
For instance, the teams looking at samples from the Bennu asteroid have found amino acids, nucleobases, ribose, glucose and carboxylic acids.
That would suggest that all of the basic elements needed to form simple self replicators (i.e. 'life') can form on their own. Even in an environment as adverse as an asteroid open to the vacuum of space.
I believe God was involved, he created life.
That's nice that you believe that, but science is about what you can demonstrate and have evidence for. What have you got?
We are sentient because of him, he knew where to put our fingers, our eyes, and how to make our eyes work, and our body digest food, he has made this all possible.
The problem here is that the evidence available lead to the conclusion that all of those things - sight, digestion, the shape of the primate hand - evolved over periods of tens of millions to billions of years and that humans and all other creatures are the result of natural biological processes.
But of course the scientists would say where is our proof for our belief in the existence of God, we point to Jesus and the testimony, however they want undeniable proof and facts. How do we give them that?
Scientists wouldn't say "where is our proof for our belief in the existence of God," for a couple of reasons.
Firstly, the beliefs of any particular individual has no bearing on the validity of an idea in the sciences.
Secondly, scientists would want evidence rather than "proof".
If you want "undeniable proof and facts" here's a suggestion:
Take you belief(s) and use them to make exclusive, novel and useful predictions about life. Then test it and share the finding with the rest of the world. Then make them and test them again, thousands of times daily.
That is, figure out an "if, X, then Y" statement that could only be true if your beliefs about God creating life are accurate. This forecast also cannot include anything that could be forecast from our current understanding of evolution.
