because I exist
Yes, and we have very good evidence about how you got here. So how about trying again and actually thinking about it?
The origin of all existence
Circular reasoning again. If you
define "source" to
mean "the origin of all existence" you have already assumed that it exists and that there is only one.
You really need to work on separating your premises from your conclusions.
Just think about it - - - There can't be two origins
Given your definition above, of course not - but you haven't made an argument for it, you just assumed it as a starting point.
God Himself made the connection
Back to totally baseless assertion without even a pretence at an argument.
Who are you hoping to convince with this sloppy thinking? If you have done software, you must be able to be reasonably logical. Think about what it is you are using as a starting point and how that has led you to your conclusions - then present them so it's absolutely clear what you are
assuming and what you think you've
concluded from it.
