You might as well say how can we KNOW anything?
Rational thought is simply a tag we put on the type of thinking that considers facts, evidence and reason. It is clearly the most objective way to think, rather than basing everything on unevidenced belief.
Put it another way, if we can define the parameters of what "rational" is and devise a thought experiment and ask a group of people to rationally think about a conceptual question and give a probable answer to that question, then you might expect more than a random percentage to come up with a similar answer - if this test was repeatable with predictably similar results then you could say that you were thus proving the validity and dependability of critical or rational thinking.

You are currently experiencing a lucky and very brief window of awareness, sandwiched in between two periods of timeless and utter nothingness. So why not make the most of it, and stop wasting your life away trying to convince other people that there is something else? The reality is obvious.
