Can you make a God claim?

You missed out the rest of my quote where I said that if you are throwing out current theory, this must be justified. In einsteins case, he did justify it.

That doesn't mean you can just ignore reality as you see fit without justification.

If you are making a claim which is meant to improve on previously established claims, then you need to justify why that is. It's possible the claims before were wrongly accepted.

Maybe I didn't explain that very well in my OP. Sure, there are always issues of epistemology and so forth. But we're dealing with demonstrated knowledge and theories, which we are justified in thinking is correct based on information at that time. I'm not talking about absolute truths, only practical demonstrations beyond reasonable doubt.
