It's only your misunderstanding and fad faith that suggests that the proof for God has been debunked.
Get write in here. Write the debunking out yourself. If you don't, you are showing you don't have any.

Sure, your argument is based on cause and effect that you keep mentioning every single thread. Even if everything has a cause (which we dont know) your argument fails to prove what the first cause is since it provides no evidence for it. You say it's god but it could very easily be something else or gods or multiple causes or the universe may not even have a cause or maybe a multi verse exists.
Cause and effect is so extremely overwhelming in everything that we see, that science has made it a scientific law and principle... one of the basic laws and principles.
The thing that would be opposite of cause and effect, would be pure random. Study pure random to see that there is no example of it anywhere, and that such a thing is impossible in an ordered universe such as ours.
We are so extremely limited in our understanding about much of anything, that it is very difficult to see what God is made up of. If it takes thousands of angels to "build" the universe, then thousands of angels, combined, are God. If it takes a wisp of stardust to make the universe, then that stardust is God. If the holes in big bang theory were ever filled, then BB might be shown to be God.
Not that I want to get into religion here, but the Bible talks about the Holy Trinity (without using the word Trinity). God is made up of 3 Persons in one God. The Revelation talks about the Seven Spirits of God (Sevenfold spirit of God).
The thing I am talking about is God, not what He is made out of.

So a wisp of stardust is god. Horace, you definitely have a new episode here
