Once, one friend of mine that was given to this phylosophies, and who showed me this argument, went even further: we cannot prove that even yesterday really happened. The universe could have been created today, and we could have been created today too, but our minds filled with memories to simulate that we were here before, and that we had a past.
Nobody will say for sure that the earth was created precisely 4.56 billion years, 3 months, 12 days, 8 hours, 50 minutes, 23 seconds (...) ago. What can be given is rough estimates, as accurate as possible. And in geological time, being off for 500,000 years isn't bad, for instance.

Your friend is correct, but if you wave out all logic and say "yeah, anything could have happened, let's disregard everything we know, even tho everything we know points in this direction", then you're letting go logic, and there is no further discussion possible.


That is the same as saying this could be a simulated universe and that some really advanced alien civilization is simulating our reality. Yup, possible, but how does that help us better understanding our universe ? If you try to answer the big question with that, then you've created a bigger problem -- how did the advanced alien's civilization universe came to be ?
