Tell us about the dinosaurs

[Anomalocaris]

If something exists then there should be a way to test for it.

There may be life on worlds in other solar systems.

We dont know if this is true and we cant test for it now, but we can theorise on ways to get this information.

If we cant even theorise on ways to test for something then its a good sign that it does not exist

According to whom? Did gravity not exist 3000 years ago because nobody had theorized a way to test for it? I am thinking it did.

True.

But there were older theories of gravity, most famously aristotles theory which predicted that the heavier of two pbjects would fall the fastest.

This was refuted by galileo who dropped a ball and a feather off the leaning tower of piza (mmmm Piza).

So it wasnt that no one had noticed it and Newton went 'what was that' its just that the older theories were less focused not worked out mathmatically and wrong.

Is your point that there will someday be a test for god?

I wont hold my breathe.

Actually, this is beyond ridiculous. While no one in the early iron age may have theorized a modern theory of gravity, everyone 3000 years ago who declines to jump off a cliff has theorized a 1000 BC theory of things falling down, which they put to daily and fairly rigourous test by emptying their chamber pots out their window, hopefully onto the heads of the 1000 BC equivalent of Statler.
