When I was 20's, I had read Schopenhauer's books. Among them, his doctrine on creation was quite impressed to me.
He said that even a god can't create a new thing out of nothing. This word "nothing" he said means absolute emptiness, but nichts.
Because the emptiness means absolute nothing. It is just empty. How can even a god create something without anything? empty once keep forever empty.
If the god create a new thing with emptiness, we have to know that emptiness we regard can't be real emptiness. I mean, sometimes we as humans can't help recognize nothing as emptiness.
I mean, It comes to the god as nothing but comes to us as emptiness.

He tried to explain how come this universe could be created with such theory.
There was universe as a sphere and then, someday it exploded like big bang theory said. Bang! It has been universe today.
In order for the sphere called universe to explode, in any case, it requires power,whether it is from its inside or from outside. What is that power?
Philosopher Schopenhauer thought we don't know it, even can't imagine it. It is limit of cognitive ability of our humans, but we can call it a god or god's power.

Anyway, Nietz´sche who was deeply influenced by Schopenhauer's and we can call him one of Schopenhauer's said the god is dead.
A lot of philosophers think this saying of his words indicates there is no absolute truth.
It looks like to be too long for me to persuade and understand you that his words are right.
But he didn't say there was no god, he just said that the god was dead. So it means there has been a god like Schopernhauer said.
Considering process of creation of our humankind or this universe logically, you can easily understand that in the beginning steps of those creations, they needed powers.
You don't know what shape the powers had been or what they really were or where they were from.
After thinking for a moment, you can come to this conclusion that you don't care whether they were from the real god or they were themselves the god.
Now you can see this matter that we might not know anything on truth.
I mean, as we can't know that it is from whether the god's power Jesus said,the god's power Muhammad said, or the Buddha's power, we should agree that there are something we can't forever recognize since we're humans.
So it is not wise way for you to appear that you know everything on your religion and look down another religion.
But who know that we,humanity each other calls different names since there has been originally only the god?
