So...guess I'm the new guy

Am I your English teacher or something?

assumption/əˈsəm(p)SHən/
A thing that is accepted as true or as certain to happen, without proof: "they made certain assumptions about the market".
The action of taking or beginning to take power or responsibility: "the assumption of an active role in regional settlements".

Therefore mathematics must have no proof or evidence behind it to be an assumption, let alone one which is metaphysical. Logic and mathematics have real world results and consequences. It has proven accurate on almost all accounts and has never failed us. It certainly didn't fail us when we used mathematics to calculate how to put a man into space and technology developed using rational thinking, scientific approach and logical deduction to put theory into practise. Most would see that alone as evidence and it isn't the only case that illustrates my point, infact there are countless I could use.
So please, elaborate on why logic and mathematics have no evidence or proof behind their validity and are therefore assumptions.
Then explain what makes these assumptions related to the metaphysical as opposed to simply being conceptual.

No-one claimed it accounted for all of reality. We haven't even properly explored our universe yet, such a sweeping statement could not be made. You are making the claim it definitely doesn't work without any examples where it doesn't work. Yours is the only sweeping statement made in this thread and it is yet to be even remotely justified.

I'd like to see some scientific evidence for the existence of mathematical truths. Can I see some please?

So the trajectory and specifications of the spacecraft that put men on the moon being accurate despite a huge potential margin of error that could result in disaster isn't evidence?
Is that what you're saying?
