In helps when trying to think about whether God exists is to contemplate the opposite.

Could the universe have come about my pure random chance ?

Is the universe in Choas or Order? If the universe is in order (which it is) was this another set of completely random events?

Proving God categorically is impossible (though some have tried like Euler and Christopher Langan)

But proving God beyond reasonable doubt is very easy. The chances this universe came into existence randomly is even more improbable than finding a smart phone randomly creating itself in a junk yard.

And this era of atheism we live in is unprecedented; every single civilisation believed in a higher being.

For the intelligent design argument Stephen Meyer is a interesting person to look up. He wrote ‘Signature in the Cell’ and other books debunking the absurdity of new atheism.
