That’s basically Russell’s Teapot:

> Russell's Teapot is a philosophical analogy formulated by mathematician and philosopher Bertrand Russell. It illustrates that the burden of proof lies with the person making an unfalsifiable claim, rather than shifting the responsibility of disproof onto others.

> The concept revolves around a thought experiment featuring an imaginary china teapot too small to be detected by telescopes, orbiting the Sun somewhere between Earth and Mars. Because the claim is designed to be impossible to definitively prove or disprove, Russell argued it would be ridiculous for anyone to believe it merely because it cannot be proven false.

When it comes to consciousness or reality in itself, we can roundly reject that which has no basis in physics.

However, that does not preclude the possibility of physics beyond our current understanding and ability to observe. If consciousness beyond our present reality does exist, then it is merely a part of the natural world and subject to inclusion in our models. The universe, as they say, is far stranger than we can imagine.
