And here you start being wrong again. We are fine with doubt. We acknowledge it when it is there. That is the whole point. This has been explained to you in many different ways multiple times now. How come you do not understand this?
How do you know such a spiritual realm exists? Again you are making assertions here without giving us the slightest reason to believe those assertions are true. This has also been explained to you multiple times now.
More assertions without evidence.
"We are fine with doubt. We acknowledge it when it is there"
Toward earthly matters about science sure. About existence in the Creator - He is mocked and left out of the public school systems and textbooks. Who are you kidding?
"How do you know such a spiritual realm exists?"
There came a point in time when learning earth science and the limitations of Naturalism that I became open to "if" there was a Creator. And I approached Him, the Creator of the universe we live in, on "if" He was and "who" He was. It was in heart and words within: through openness and through sincere prayer. It wasn't to prove something to someone else; it was to know truth about the most important issue in life. To say the least He gave a "spiritual" reply - through His Spirit. I was "baptized" by His Spirit.
So many people say it is foolish to seek if there is a God. Like it is so primitive or immature. Like we should already know that there is no God or Creator that is detectable.
There are also so many people who have "words of men" about Him. Even words from Naturalists. So many people never singularly seek Him. They never go to the Source and seek the Creator of this Creation. The result is they hear many things and have second or third hand knowledge about Him and the spiritual world.
In Romans 8:14 it says: "For all who are being led by the Spirit of God, these are sons of God"
In John 16:13 it says: "And when He, the Spirit of truth comes, He will guide you into all truth"
We are to go to and follow Him, not men. The Scientific Method has use in the physical world but it also has limitations. Major limitations on matters beyond the physical.
