100% certainty doesn't solve anything.
For the sake of demonstration lets say that I am 100% certain the apple on my desk exists.
Then I induce that something MORE than the apple exists. Lets call it.
The... Earth!
But if the Earth exists. Then I can further induce that something MORE than Earth exists. Lets call it...
The... Solar system.
But if the Solar system exists... Then I can further induce that something MORE than the Solar system exists. Lets call it...
The...Galaxy!
But if the Galaxy exists. Then I can further induce that something MORE than the Galaxy exists. Lets call it...
The... Universe!
But if the Universe exists. Then I can further induce that something MORE than the Universe exists. Lets call it...
The... Multiverse!
But if the Multiverse exists. Then I can further induce that something MORE than the Multiverse exists. lets call it...
The ...Multimultiverse.
But if the Multimultiverse exists. Then I can further induce that something MORE than the Multiverse exists. lets call it...
God!
Like Anselm did. But why stop there?
If God exists. Then i can further induce that something MORE than God exists. Lets call it...
GodGod!
So it is clear to me that if we are going to be using induction then saying 'ALL-THERE-IS is the universe' is completely unjustified.
ALL-THERE-IS is GodGod is a premise with equivalent truth-value.
And we can go on saying "ALL-THERE-IS Is GodGod" and GodGodGod. And GodGodGodGod.
So you need to explain to all and sundry why you have CHOSEN to draw a line at 'the universe'. Perhaps you have run out of imagination?
After all the notion of "induction" comes from Mathematics. And the principle goes roughly as follows.
* Assume that a proposition is true for N=K.
* Prove the proposition is true for N=K+1 also.
Then the proposition N is true for all values of K.
But what if K = ∞? Then the proposition is also true for ∞ + 1 !
Mathematicians solved this problem by simply saying: ∞ + ∞ = ∞
And then we can have a debate on whether ALL-THERE-IS is infinite or finite.
But apparently Mathematics doesn't matter, so I guess Age is out of this discussion.
