Science isn't about some abstract idea of 'truth' but about what fits. You have to demonstrate some kind of approximation to what happens- otherwise it's not science. And it's what happens that is the ONLY test. So you can come up with many models that fit the observations- and they only differ when you use the model to predict the NEXT observation. That's when the science happens.

You can make up as many different explanations as you like, but until you come up with a test by which you can demonstrate that one explanation is better than others, and it must be a test that other people can repeat, it's just so much hot air.
