If as a scientist, you study all forms of life on earth, past and present. There is one are that science has yet to discover about all of that life. Where and what is the actual source of the 'life' in every cell? Everything that is 'alive' has this special spark that makes it live. If it loses that life, that spark, it stops living as we know it. If you really think about this fact, then you will find why I believe in God. At the very beginning something or someone had to put that little 'spark' as I call it within the earliest form of life. That to me the proof we all seek...it is all around us and within our own mind!
I have read a few studies where science has developed a hypothesis of how an organic chemical reaction could create this spark of life. It was interesting but they had no data or experiments that would even answer what the spark of life really is. So, the more I read, the more I was convinced they really don't know...
