Vlad,
As you're still ducking and diving about this I’ll try again: WHAT MAKES YOU THINK THE UNIVERSE IS CONTINGENT ON SOMETHING OTHER THAN ITSELF?
"contingent on something other than itself" is a tautology.
So what you should have properly asked is
What makes you think the universe is contingent?
It is a composite dependent on it's existence on it's component parts.
No components no universe.
So it is contingent not because of the contingency of it's parts
But because it depends on the existence of it's parts.
Your welcome.
