It is fine if you disagree and I believe a lot more people will disagree with this philosophical position as it is not very popular these days.

Near-death experiences, out-of-body experiences, contact with 'immaterial entities' and so on hint towards an existence beyond our material reality. Since there is no way one could 'scientifically' test these does not mean these things simply do not exist.

Testimony widely used yet mostly dismissed method of knowledge acquisition establishes all of the above:

A patient being operated on while in a complete medical comma explaining the things happening in clear details in a nearby room after the operation that there is no way they could have known that, one such testimony by a reliable person is sufficient to establish that our current understanding of the world is insufficient. And there are so many of these.

I am not saying u have to change your worldview just because I am saying so. do your research. the world is much bigger than what is out there on the internet. (pun intended)
