Is your ultimate position that there is no first cause?
No.
The Big Bang requires gravity and other things to exist.
Maybe.
So far this discussion always ends in an infinite loop of some sort.
If the loop were infinite, it wouldn't end. It generally ends when you get start ducking and avoiding questions.
When I am programming I know immediately when I have accidently created an infinte loop because whatever I am working on will crash.
Remind me not to use any code you write. If it crashes, the loop isn't infinite. If it truly is, you generally have to attach to the process with a debugger and break in to see what it going on or set breaks in the code and step through to see what happened.
Even the simplest task when put in an infinite loop will crash the fastest system.
10 PRINT "this is not crashing"
20 GOTO 10
That code wouldn't crash a PC Junior when I was 14, bro. Infinite loop.
boggles the mind
I can see that.
