Can UFO's diminish our religions?

What I would like to know from the religous among us is this:

If an alien species did come to Earth and tell us that we were created by them in a scientific way, such as DNA manipulation. And they also provided proof such as records, videos of scientific work and detailed records and examples of the history of the precedures.

What would you all think of god as the creator of man then? Would you all start worshipping the aliens as god?

i think Christianity would get a blow. Losing allot of believers. Islam would lose some in the begining but the koran says: Allah the creator of all worlds. I think they would gain regain enough to get them back to level and continue to grow after that.
