The idea of needing proof is philosophical, not scientific. There is no evidence that we should be skeptical, it's just the philosophy that makes the most sense.Anyone who claims something has a burden of proof to that claim.
Even asking for a proof is claiming something, because you think you know what the proof is, how it should be laid out, what it will look like, and so on and so on. I could very easily ask why that proof is proof, and then ask why the proof of the proof is proof and so and so on.
And no, no claim is made by asking for proof. When i wanted proof that e^(i*pi) = -1 i didn't know what i would find, i had no idea how it would be "laid out". In fact, what i found completely blew my mind.
