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

[Aoi Magi]

Ok. Here is the "brass tax": do you trust people based on how they witness to what they say, or do you not?

The issue of the existence of God is separate. You can prove that with paper and pencil, no need look for miracles - just look for there existing ANYTHING, and realize that causes and effects, contingency, corruptible composition, and intrinsic purposes are all clear and infallibly point to the need for some First Cause which is uncreated, simple, infinite, etc., which we call "God." That God entering into creation by act (and by flesh) is something else... You are conflating the two. The first is answered by philosophy, the second by theology.

My suggestion is to stop playing cat and mouse with miracles (and other opinions, especially the most unfriendly ones, as puerile as their critiques tend to be) and read the New Testament instead, recognizing at what horrible personal cost those texts were written and transmitted over the Earth by those who claimed to have been there and saw it all for themselves or to have spoken at length with those who were there.

This guy seems to feel like God's existence is undeniable due to the fact that cause and effect is a concept. Doesn't really seem definitive enough for me.

It always amuses me how god must be uncaused, infinite, e.t.c yet somehow those properties cannot be applied to our universe. Moreover, even if I concede there was a first cause, how you get to a sentient creator from that, even philosophically is beyond me.
