Nothing in Science says "God does not exist".
Nothing in science says God exists, why would it say it doesn't exist if it doesn't even assume it does?
I'm not sure what your question is.
As a person of faith, I'm of the opinion it is impossible to prove the existence of God.
We can see patterns and code re-use occurring in nature, but again, it's just conjecture, hypothesising and speculation.
Where others may choose to see "The fingerprints of God" everywhere, I simply see natural processes.
