Because of the elimination principle of False, if you can prove it then you will be able to also prove any other sentence. This would be a disaster because there would not be any interesting distinction between sentences. All sentences would be provable, there is a proof that 2 + 3 = 5 but also a proof that 2 + 3 = 9 and so on. So we hope not.

You probably want to use Falso for this https://inutile.club/estatis/falso/
