To agree with you then you have to answer my question in scientific manner.
Did nature always exist ? and how did you know such fact ?
IOW , Did the nature existed before the nature and hence nature was always existing.
Here's the thing. Science will, at any given moment, always have a frontier. There will always be scientific mysteries. But science is dealing with them one by one. Slowly, gradually, we are penetrating these mysteries. You seem to put your god in that boundary beyond what is known, but that boundary is getting pushed all the time and so, by your own logic, your god is getting smaller and smaller.
Isaac Newton was also a fan of the 'God of the Gaps'. When he had done the laws of gravity and physics and suchlike he reached a point where he couldn't solve certain mysteries (he was limited by the tools of his day). So he said 'Maybe that's where God is. Maybe that's where God steps in and sorts things out.' But all of those 'mysteries' he said were god have long been solved and are now taken for granted as fact. So if you're alwyas going to put god into that point of mystery science has not reached yet, eventually your god is going to vanish.
Still waiting on the egg explanation, incidentally.
