“Atheism fails miserably.”
That would depend on its goals, right?
“First of all, in order to be an atheist, you have to believe that there is no Creator.”
Yes. That’s what ‘atheist’ means.
“Secondly, in order to be an atheist, you have to believe that we somehow arrived without a Creator.”
That’s second? Isn’t that part and parcel of not believing in a creator?
“Thirdly, in order to be an atheist, you have to believe that we arrived here other than on purpose.”
You’re just repeating yourself, here. If there’s no Creator, nothing that happened had a creator creating it.
“Fourthly, you have to believe that intelligent life came from a non-intelligent source.”
Do you have any actual evidence that it cannot?
