I am new to this forum and this is my first posting/reply btw.
I have never heard of Kalam before, but here is my first reaction.
Please define “cause”. By “cause” do you mean having a reason for existence, or a purpose, or a goal? I don’t think we CAN know that about the universe. I think “god” of any faith system is a made up fantasy/explanation to relieve the stress of un-knowing. Mankind makes things that have a purpose, a causal use. We also tend to want to explain and define everything, and are uncomfortable with insecurity and chaos, and uncertainty. What evidence suports the claim that the universe has a “cause”?
