Creationism

[GrandizerII]

Kalam's first cause is temporal first cause (as you go backwards in time, eventually you get to that first cause).

Aristotelian/Thomistic is an atemporal type of first cause. Assume time is frozen, if you go "downwards" (for lack of a better term), eventually you get to that first cause.

Kalam: everything that begins to exist is caused.

Aquinas: everything that requires cause is caused

I find this Wiki page to be overall fair because it does reflect current status of discussion on Aquinas' Ways. Unlike with the Kalam, atheists have yet to come up with something strong against these arguments. This doesn't mean there aren't reasons to reject them, of course, but effective counters are nevertheless currently lacking.
