Seeing a light fly over at a scheduled time does not prove it is what they say it is. I have yet to see positive proof of it.
Agreed. When you feel your heartbeat, this is not necessarily proof that you have this organ within you. Positive proof is needed. In fact, according to this train of thought, you have no positive proof that you were born (doctor conspiracy), or that your parents are really your parents.
So many things are suspect......why bother caring about the shape of the Earth? You do not even have positive proof of more important aspects of your life.
You see, with this ideology, you have created your interpretation of this world to boil down to one of two things. Either:
A) everyone else on this planet is crazy
or
B) you are.
And that's quite a pickle.
