If science is to be brought up, it is unscientific to rush to a conclusion when no conclusion has been reached through verification using scientific methods. It's not a question of denying or affirming.
Research is progressing in quantum mechanics... You told me an interesting story. I'm interested in this. However, during the research, it is just research in progress, and no conclusion has been reached. I don't understand what I don't understand. If you can't stand it and come to a conclusion, it's just that you are succumbing to the psychological stress of not understanding.
Such research results have been obtained from fields related to cognition.

But I'll prove the spirit! If you say that, that's the spirit and goodness. It is unscientific to regard one study or one scholar as sacred and not doubt it. The same goes for quantum mechanics, so please do your best.
Now, what did the Buddha say about spirits?
In an anecdote called “The Parable of the Poisonous Arrow,” to an apprentice who had no choice but to worry about things after death, the end of the world, etc., he said, “Please practice without thinking about things you can't come to a conclusion even if you argue!” I was scolded. The Buddha did not mention whether there is or not, and he said, “Even if you think about it, it only interferes with peace of mind.” Therefore, this teaching is called “ignoring.”
On the other hand, it doesn't mean that the afterlife isn't mentioned at all.
“Live honestly. There is no time to list the sutras that say, “If you do, it will be easier in the next life.” However, these kinds of teachings are definitely words for royal aristocrats and common people, in other words, non-monks. What is the message of this word? Will it be an afterlife benefit? Or is it the part where you have to live honestly? The monk's opinions are also divided depending on how they pay attention.
Personally, since the Buddha is also a monk, I think the teachings for disciples who became monks would be closer to the true intentions of the Buddha himself than the teachings for the general public. That's why I believe the main message for the general public is to live honestly. (CF, counterfactual theory, Brahmin religion)
Speaking more deeply, the afterlife that Buddhism preaches must be read on the premise of “all laws and nothing.” I don't have the number of characters anymore, but it's a teaching written by Master Tange.
