Are ID/YECs right about anything?

It's well past the time when it was possible to argue against the theoretical age of the Universe and/or our Solar System. The only way that scientists can be mistaken about these things is if your deity deliberately intended to deceive Mankind.

Would you say that's likely, given your belief system? Is your 'god' the great deceiver?

Nothing had to be a deliberate deception, if we make a mistake due to how we look at things, that is on us, not God.

A deception would be if scripture was false, that would be a deception.

And suddenly I feel as if I'm in a conversation with the guy who insists the Earth is flat, lol.

If a person believes in young earth creationism and claims that all the evidence of bygone, geological ages isn't there to test us in our belief or there to deceive us, then that person is missing something rather important and can be ignored.

Seriously, this is where you go?

No it isn't, regarding the universe. That's completely up for grabs.

YEC isn't science. It is failed apologetics and an attempt to substantiate what is already believed.
