Question

What are the fundamental factors why science accept darwin and bigbang theory?

Answer 1

They are the same fundamental factors that lead scientists to accept every scientific theory, such as atomic theory, quantum theory, Einstein's relativity, plate tectonics, germ theory, number theory, etc

http://en.wikipedia.org/wiki/List_of_the...

All accepted theories have a broad set of reproducible observations that lend support the fundamental ideas. All theories have predictive power and can make predictions about future observations. All accepted theories are provisional - they change as more data becomes available.

"A theory makes generalizations about observations and consists of an interrelated, coherent set of ideas and models."

Answer 2

Because both theories seem logical and scientists tend to follow the head [ logic ] over the heart [ emotions ]. Neither is, however, absolutely 'provable', so they remain popular until a newer one comes along ! Remember 'scientists' have been proven to be wrong many times in the past.
