What is the meaning of reason and cause?

everything in this world is based on reason and cause!!

everything(phenomenon) in this world needs a reason or cause for it's existence(for being created)!!

pay attention carefully: thing A doesn't exist, something else cause its existence and it comes to reality(becomes phenomenon)!!

mankind finds out this important issue in this world and proves a lot of happenings around himself!!

this issue is the basis of any science!!

theists use reason and cause to prove existence of God!! God is the first reason of the worlds!!!!

he does not need any reason, because he is not phenomenon!!

Wouldn't they be at odds with each other, cause being part of the sequence of "cause and effect to cause and effect," and reason being the conscious deliberation of choosing an action that a person thinks is free?

The reason is why and the cause is how.
