Kant self refutes. It fails its own standardsAnd Kant showed how all were faulty.
Many uncaused causes just pushes things back. You still need an original cause. Infinity does not exist in reality. Most of your assumptions is no more valid than Star Trek's transporter room. It is Science fiction.#2 is based on causality, which we know fails at the quantum level. It also assumes that the process cannot go on to infinity. And, finally, it only shows that there are uncaused causes, not that there is a first cause (there could, for example, be many uncaused causes).
if ever a time there was nothing then there cannot be anything is valid. From nothing comes nothing. Nothing cannot produse anything.#3 is based on the flawed philosophy of necessary and contingent existence. Again, an Aristotelian viewpoint which is known to be wrong.
Design does not need intelligence is an illogical assumption. To have design you need intelligence. On your point 2, here are some responses from Christian sites which will be ignored.#5 is based on the idea that complexity must be produced by an intelligence, which we again know is incorrect.
Sorry, but your medieval 'proofs' simply don't hold the water you want to carry.
