We looked for answers for thousands of years, how we got here, why we die, why there are natural disasters, what's the point of our existence. Sometimes people say religion prevented us looking for answers and hindered the development of science.
The history of science course I studied at university theorised that people's belief in God lead them to look for laws in the natural world because they were sure a creator would have made laws. This, they think, lead to science as we know it. It's an interesting idea.
Personally I wish the whole world would see that we've grown out of organised religion but I guess that's going to take some time.
