This is completely unwarranted judging from the rest of your post ("in the very infancy", "nearly completely unknown", "mostly in the dark", "haven't the foggiest idea"; although I appreciate the frankness).
If people made bold statements like "There is no such thing as X" in any other field at a similar stage of development, their claims would be rightly dismissed as pseudoscience. ("There is no such thing as a graviton. Full stop.")
Your claim is not a finding of your field of expertise, or any other branch of science. It's metaphysical belief. You're entitled to it. It's a widely shared belief. It might be a belief with a lot going for it. Metaphysical claims are fun! They can be discussed! But I wish people wouldn't confuse them with scientific knowledge.
