First of all "God" is only a word, a sound, or vocal vibration.

Personally I believe the Universe has always existed in some form or another. The problem human minds run into when thinking about "creation" and our origins is the concepts of time! Time is very tricky...as it is subjective in nature...AND it is well known that time is relative to our own personal experience when we smoke cannabis. So, an eternal universe is rather hard to fathom from our perspective. We cannot know at this moment in the game exactly how or why the universe created us (abiogenesis) but we know that homo sapiens and all life are most definitely a product of evolution.
