What beliefs would we consider reasonable for a self proclaimed Christian to hold?

[Angrboda]

The burden is on you to prove intelligent design not for us to prove that it's not .

That is very convenient for you isn't it? Your whole premise is based on happenstance. You do not have any testable evidence that life began on earth when conditions were just right yet you expect proof from me.

Whine all you want, but you still need to demonstrate intelligent design. A negative argument against abiogenesis is nothing more than an argument from ignorance.
