Sure we can know. God told us so. The simplest explanation is everything looks like it was created through a process because it was created through a process. There is no other explanation that would lead to a greater glory. God isn't trying to trick us. He told us he created the material world in steps and that's exactly what we see.I don't know it wasn't. I don't know it sprang into being billions of years ago, either.It would be illogical for God - who is logic - to create something that was a lie especially when it is not needed and would serve no purpose. That's how I know the universe was not created 10 minutes ago.My personal beliefs are immaterial to the purpose of this thread.So then you don't agree that the Bible tells us that God revealed himself to man and revealed that he created everything for His glory?A finite mind cannot comprehend an infinite mind. Who can say what the creator's purpose is?Ok... if God wanted to convey His glory and power by creating a universe all at once, God would have created the universe to look like it was created all at once. There would be no logical purpose to create a universe all at once and make it look like it wasn't. So it would be illogical for God to create a universe in this manner.Disprove it, then.You can call it a thought experiment but it's a paradox and like most paradox an invalid argument.A thought experiment is a hypothetical situation in which a hypothesis, theory,[1] or principle is laid out for the purpose of thinking through its consequences.A fish does not know it is wet. So a fish would never try to prove it was or wasn't wet.In this experiment, there was no universe and therefore nothing existed 11 minutes ago. No matter, no energy, no physical space.
Then God created the universe 10 minutes ago, exactly as it is right now, with all the evidence it's billions of years old built-in, with the light from distant stars created in transit, and us with all our memories of a lifetime in place.
Now...how could you disprove this? NOTE: Emotions are not proof. Hostility to God and insistence He's not real is not proof.
Same thing applies here.
But if you want a valid answer to an invalid premise I could disprove it because it wouldn't be logical and God is logical.
A greater demonstration of power and glory would be willing existence into being such that everything unfolded logically over time according to God's plan through the act of creation and the laws of nature.
How do you know the universe wasn't created 10 minutes ago?
No one can know.
