So, no-one's proved that God exists - yet. And its far more difficult to prove that something DOESN'T exist.

On the contrary. We can quite readily point to a time when God most certainly didn't exist, and we can look at how the idea of monotheism evolved from preceding pantheons & mythologies. We can also look at other cultures and religions for whom the very idea of God is anathema, if only to show that even in our own time the God concept is far from ubiquitous.

In nature, there is no God. The idea only exists in humanlore and has no basis in reality. Humanity created God simply because they didn't know. Now that we're at least beginning to, the idea has significantly less appeal. Indeed, the very idea of God is synonymous with an arrogant & aggressive righteousness that would insist that even the galaxies we see in the famous Hubble eXtreme Deep Field Image which are up to 13.2 billion years old, are the work of a God we only dreamed up (at best) 4,000 years ago.

Ergo, God doesn't exist. Simples!
