Not really, depending on how you define "God."
Here's a proof about the nonexistence of Yahweh and Allah, in four paragraphs:
There's no reliable evidence for Jesus, Yahweh, Allah, Zeus, Thor, or any of the thousands of other gods that people have worshipped. There's also extensive evidence that they are all just myths, created to help soothe our fear of death, and perpetuated to subjugate the underclass into obedience.
Science has shown that there's no need for gods to explain the traditional reasons for a god -- origin of the universe, origin of life, origin of species, origin of humans, origin of morality. Science also shows us the psychological reasons that people believe in god(s).
If a god like Yahweh or Allah existed there would be explicit evidence. No such evidence exists, therefore these gods do not exist.
Yahweh and Allah are also internally and externally incongruent, and thus cannot logically exist. An omnipotent and omniscient god with free will can't exist, because it could not both know the future and change it. An omnipotent and omnibenevolent god can't exist and allow the true horrors that occur to sentient beings.

Why should anybody believe anything from the Bible? It was written by primitive men who believed that the Earth was flat and covered by a large solid dome called the firmament.
