Now if they were to say "we don't observe the interaction of gods, therefore we should be agnostic or deists" then I'll have no problem with that but since many atheists are going around making absolute claims like religious people then it's a problem, more so when the statement "God does not exist" has no empirical evidence to verify it. The onus isn't on the theist at this point as this statement implies the atheist speaker has access to knowledge which explicitly debunks God's existence but no atheist has yet to produce any. Their argument of "I can't see" falls flat on its face as there are many properties of the universe that cannot be seen but exist.
In truth, atheism and the denial of a god seems to be caused by emotional thinking caused by the troubles of real life (i.e religion being a bad thing for them, the problem of evil, suffering, etc) rather than actual rational thinking about the universe. It's funny, because in denying a god, many atheists recourse to the hypothesis that the universe simply came from nothing (this itself has zero evidence and exists in science only as a hypothesis fueled by the pure speculation of the biased anti-theist "Lawrence Krauss"). The hypothesis of a universe from nothing is so contrary to the laws of this universe and causality that it's amazing how many atheists support it thinking that it's logical. The idea of a god (whilst also lacking empirical evidence) at least has the support of philosophy and cause and effect. The Prime Mover argument is simple, if the universe came into existence then logically it had an eternal creator.
Other atheists recourse to the "infinite chain theorem" which argues that each universe came from a prior one but this begs the question of where the first universe came from since in this model, it couldn't have been eternal. Without a start, there is no instigation so this theorem falls flat.
However you look at it, there's only two ideas. Idea 1 being an unmoved eternal mover (God) and idea 2 being something from nothing. Also, the theist can rightfully argue that if matter and space-time can come from nothing then why not a god or a "universe" that itself is conscious that would fit our definition of a god?
I just find it humorous how atheism attempts mental gymnastics to try and explain away God.
In fact forget "atheism makes no sense rationally." Atheism makes no sense at all!
