Here's a proof (simplified) of no God.
Science yields this equation:
Power = mass x stuff
Claim: God is immaterial (i.e. no mass)
Plug in zero mass:
Power = zero x stuff = zero
God's power is zero. This means he does not exist. This equation shows any immaterial being like God, Satan, Vishnu, Brahma, Zeus, and Thor and ghosts all have zero power.
