Discussion on god existence part 1

I had a debate with a very respectful and intelligent Muslim u/Particular_stage4782 ,I myself hold an agnostic stance.we discussed the meaningfulness of metaphysical propositions exactly"god exists",how do we verify the existence of god,the principle of sufficient reasoning, causality, the Kalam cosmological argument, the argument from fine tuning,and quantum cosmology....I decided to split it into parts so it doesn't be a hard read ,and here's part one,I hope this maybe helpful.
