Arguments Against Thomistic philosophy

[Astreja]

Do you or some other atheist have a good argument for how the First Cause (or Prime Mover) could be something other than God.

I see First Cause as a contradiction in terms.  "Cause" indicates the ability to take an action, but action requires energy; therefore, energy had to exist before the alleged First Cause acted.

"Second Cause" might be the closest you can get to a creator-god.  Creation from nothingness is absurd because creation would require energy, and energy isn't nothingness.
