Atheists, tell me, a Roman Catholic: why should I become an atheist?

[Balaco]

All I'll say is that when I was having serious doubts, I prayed to God to show me in a way that I would know for sure that he is real.  Now some 16 year later nothing has ever happened.  So I can safely conclude that either:  A.  God doesn't want me to believe in him, or B.  God doesn't exist.

I had a similar experience with a similar outcome.  I finally came to the conclusion that the idea of an all-loving god who loved me more than I was even capable of loving would not lay down one right path, allow Satan to lay down tens/hundreds of thousands and then simply expect me to find the one right path on my own with the intention of lighting me on fire for all eternity if I were tricked into choosing wrong, as the Bible clearly says most people searching will be, was a massively idiotic idea.

I was taught that God doesn't give us undeniable proof of his existence as a test of faith...those with righteous minds would find him. Joker and any other Catholics, what are your thoughts on this?
