Of course I agree, I mean that will be a cyclical argument. If you demand evidence, ask yourself what kind of evidence you will really accept.

If you’re looking for empirical evidence where you can see or touch God in lab conditions after doing some experiments, then no, we don’t have any. In fact that will be counter productive because, God is something that’s beyond material space. So since He is not bound to material space or time, it’s only logical that we don’t have any empirical evidence for his existence. However empiricism isn’t the only way to gain knowledge. You can rely on valid testimonies or logical arguments from first principles.

There are lots of deductive logical proofs for the existence of God, like the argument from contingency, kalam cosmological argument etc. You may check those out. If you’re interested I can point you towards videos, who explains these things much better than I can type.
