Syllogism is deductive reasoning in which a conclusion is derived from
two premises. So rationally, if something has been made, it must then
have had a maker. It could have not made itself, because at first, it
didn't ask.
I will theoretically suppose with you, that a deity doesn't exist.
Then how could we rationally construe the perfect design of this
universe? I urge you not to beat around the bush and think before you
give an answer.
