It rained.  HEAVILY.  For 40 days and 40 nights.  DUH!!! 

For 40 days and 40 nights would NOT be enough to flood the entire earth ... DUH! 

Do you know how the Oceans were formed?  It rained for MILLIONS of years, not days!
If evolution is true, then where did the demonic beings come from?

Demons are Spiritual beings.  Evolution deals with how organisms are thought to have developed on EARTH.
The result is that the propositions of a religion are treated not as independent propositions deserving of inquiry, but as the defendent in a trial with the believer acting as defense counsel with the goal of "proving" a predetermined conclusion. I.e. the propositions are true until proven false. Acting in such a manner, a believer can suppress or avoid evidence, make impassioned emotional pleas, attempt to shift the burden of proof, be under no obligation to carry out investigations which are likey to damage their case, etc.

How true!  You are a very intelligent man.


Now how come no one answered my question where Cain got his wife from?
