God Is Or Is Not.

[Theland]

If God IS, then all of our big questions about origins, are answered.
If God IS NOT, then the alternative is purely materialistic.
What do you say?
Obviously there are atheists who believe the latter. So please guide me to the evidence for a purely materialistic origin, beginning of life, and evolution.
Please feel free to guide me towards any YouTube videos where atheistic experts can convince me that a purely materialistic scenario is the only option.
I am eager to understand the atheist mindset.

Very well observed.
