Quote from vhehn:
primitive man had things happen to him that scared him. things like thunder and lightening,floods,earthquakes,floods, droughts,fire. primitive man had no concept of science and no idea that there could be a natural explaination for these things. he eventually came to associate these things in his mind with gods. the concept was refined until we have what people believe today.
the larger question is why would an educated person still believe these these things today?
Even Einstein concluded there was a beginning in his calculations, and if there was a beginning, then there had to be a beginner.
Educated or not, it's harder to believe that the universe just came into existence on it's own, than to say there had to be a Creator that started everything.
I don't know had God did it, but even the "Big Bang" theory points to a beginning and suggests that the size and mass of something that exploded and thrust forward the universe as we know it was enormous. Nothing could have come into existence like that on it's own; it had to be created and if it was created, then there has to be a Creator.
