Can you prove that there is no god?

Answer 1

One viewOn the contrary I can prove he is there, you find him around to motivate you to excel in everything and stand for whatever is right. Another viewGenerally, it is not possible to prove a negative, so no one can absolutely prove that God does not exist, just as no one can prove that Zeua or Brahma does not exist. However, in each case it is possible to prove that it is most unlikely that they exist. The Pascal's Wager should really be to worship all gods, in case one or the other turns out to exist after all.

It is a fallacy, in any case, that atheists must prove that God does not exist. Normal practice is that the person who asserts something to exist must do the proving; so Christians must prove that God does exist, but after centuries of trying are still unable to do so. A famous parallel example is that if I assert that orbiting the sun between earth and Mars there is a small, perfectly formed teapot, I must prove its existence: it is not for sceptics to prove its nonexistence.

Another viewIt is possible to rule out the existence of gods that have certain attributes beyond a reasonable doubt. The traditional view of God as an omnipotent, omniscient, and omnibenevolent being can be safely ruled out, as the attributes named are mutually incompatible. If God possesses omniscience, and knows perfectly and entirely all future events, then He is not free to change what has been foreseen and is therefore not omnipotent. If He can change what he has foreseen then there is a flaw in his omniscience. His supposed attribute of omnibenevolence is incompatible with natural and human evil in the world.
