Scientists will happily agree that they currently do not have all the facts. They will therefore seek further answers..it's called progress.

Anyway. To answer the original question. I do not believe in a deity of any kind because to believe that some divine being created this universe is preposterous. The earth is about the size of a pinhead compared to the sun when it comes to how big we are in the universe. How is it that such a being doesn't care about the rest of the universe, only our little dust speck of a planet. Little arrogant don't you think?

Religion is simply the early uneducated population trying to comprehend things they didn't understand. For example a scientist (who incidentally was also catholic) proved the existence of Moses. It was fascinating really. He proved that he was simply a man at the right place at the right time. Through Geological means we know that an underwater volcano (Thera) erupted in the Mediterranean Sea. Due to the curvature of the Earth they wouldn't have seen anything, only felt the earthquake.
Now he also proved the ten plagues were a result of that volcano. To cut a long story short the river turning red was pollution from the molten lava and all the animals were essentially fleeing the volcano en mass (behaviour we see now because animals can sense when a volcano is going to erupt). The hail of fire were the molten bombs being spewed out. The death of livestock and total darkness was due to the pyroclastic cloud. As for the firstborn being selectively killed this is easily explained. Modern times we call our firstborn as the literal first born child. Back then the firstborn referred to the highest echelons of the upper class, who would be given the freshest fruit and wheat. The problem is that the volcanic ash would have corrupted this food and as they'd have been the first to eat it they would have been the first to perish.

Food for thought eh?
