And if that were the only piece of information available, you are correct in making this point. However, this is not all the information. There is at least 70k years of human history, which shows the presence of strong spiritual connection. Indeed, as long as man has been 'civilized' he has also been behaving spiritually.
If you scientifically studied any other form of life, and you noted a particular behavior in that species of life for all of it's existence, and this behavior showed evidence that it produced beneficial things for the species, which explains why it has retained the behavior... We could not draw the conclusion this behavior was irrational, made up, imagined, or product of mass delusion. We may say we don't understand the behavior, but it does seem to legitimately serve a function in the advancement of the species.
It is not debatable that humans have always been spiritually connected, or that humans have benefited tremendously as a result. It's not debatable that other animals and forms of life, do not make up things to explain their fears or comfort lack of knowledge. It's not debatable that other upper primates, who share as much as 98% of our DNA, show no signs of even the most primitive forms of spirituality. All of the "reasoning" to explain why human spirituality exists, literally defies the theories of evolution and natural selection, and contradicts everything we know about nature itself. You have to adopt a FAITH in disbelief!
"Science proves there is no need for God," is a FAITH-BASED statement.
I am skeptical on the existence of spirits, because I base most if not all of my view on objective evidence that can be discerned through the five senses. Everything you have said is not debatable is indeed debateable and will continue to be so; saying that it is not is dangerous and borders on fascism.
Even though spirits cannot be proven through the scientific method, let's assume for a moment that what you are saying is true. You are saying that spirits exist. You are opening a massive,
massive door.
How many spirits are there?
Are there water spirits? Fire spirits? Light and dark spirits?
Do they have genitalia or not? Are they like the angels?
Are they able to procreate? Do they give people powers?
Can they be harnessed for energy? Can they be farmed?
What is their weight? Their size? Dimensions? Colors?
How do they exist without being seen?
Is Golden Sun based on actual events?
How do they nest? May we hunt them? What is their flavor?
Their intellect: how high? Do they know more than one language?
Are they capable of destroying our world?
Can spiritualists collect and battle them like trainers do their Pokemon?
The questions go on, ad nauseum.
I think you have tremendous belief in the notion of spirits, Boss, but I don't think you know for sure whether they exist or not. If they can be discerned through science, I would like to know, please.
If you still believe that spirits exist, why not angels and demons? Gods? Everything else?
Imagine someone else. Imagine he says and believes everything you believe and say, except that you've swapped out spirits for any other kind of supernatural being.
And back to the numbers part, just because a lot of people believe something... that doesn't mean it's true. That's just logic. Correlation isn't causation. If many people believe something, they may be right... but saying that because most people believe something then it must be right is absurd.
