Like I said.. denial.
Because we are not living in a vacuum in both a physical and philosophical sense.
You can't build a scale model even dismissing the problems with mass because you would be building that model on a spherical planet subject to friction and air resistance etc.
And we are not living in a scientific vacuum in which we need to dismiss everything you have not reproduced in a physical scaleable model and witnessed with your eyes. That requires a bigger leap of faith than that used by the religious.
We build on the knowledge of others not start from zero with every new human.
