Evolution hasn't proven itself. I have yet to see any concrete evidence proving it.
Evolution has proven itself through study of genetics and direct micro experiments showing clear as day results. If evolution isn't real, a large number of modern medicine and applications so far wouldn't have been physically possible. Of course, there is never enough "concrete proof" for anything. For example, the Newton's Laws of Motion are absolute, and yet we carefully coin it with the terminology "theory".
However, these basic theories are the lego blocks that literally runs the entire universe. If it weren't true, we wouldn't have been able to do or make anything we have so far.
I'd go into great detail about it but this isn't the thread for it.
I agree somewhat with your scientific post ... but to say that's the cause for every single "ghost" sighting is a bit far fetched, in my opinion.
Human beings do tend superimpose labels on everything. I remember how last night in the dark I nearly jumped at the sight of ... a small vacuum cleaner, because I thought it was a person. Even after knowing and recognizing it was a vacuum cleaner, when I turned around to go back to my room - I jumped again in shock at ... the vacuum cleaner. Therefore, I will certainly agree there can be a scientific basis to ghost sightings. However ...
If your talking about ghosts being "deceased souls" or a person's memory, then no I don't believe in that. If you mean a ghost as a spirit, then yes I do.
Think about it, if a person after dieing can choose to go back on Earth ... why aren't there more "ghosts"? Incidents of ghost sightings seem to be specific to certain people and are uncommon compared to other things. Also, no one would be in Hell if they had a choice to become a ghost D:
Therefore, I believe in angels and demons - nothing more nothing less. Any true instance, not caused via hallucinatory drugs or stress, of seeing a ghost is in reality a spirit in disguise of someone who is deceased. Think about it, if angels and demons cannot die and have existed pretty much since mankind existed, they could very easily know how to impersonate someone you know because ... they've been watching that person since they were born!
Now why would an angel disguise themselves as a deceased person and manifest themselves before you? The answer is, an angel would never do that because they serve God. Therefore, the only spiritual being that it would be is ... a demon/devil.
It very well could be just a trick of the mind, I will wager that's the case 99% of the time. But, you can't simply ignore the possibility of that 1%. If you consistently see apparitions of sorts, make sure to see a doctor. They may be a real physical, emotional, or mental causes for someone to see such a thing. If that doesn't work, it may actually be a spiritual problem.
"Ghost hunters" really can't help you nor could a Catholic exorcist. Short of divine intervention, there's nothing human beings can do - we are powerless against the supernatural. My recommendation would be going to a church and asking for help there. Christians should be well aware on how to deal with the supernatural. Again, it probably was just a trick of the mind! But, there can be a supernatural explanation behind it. Just my two cents.
I find the angels and demons far fetched as well but seems to be originating from a religious belief. At least you understand the scientific aspect of what I had explained.
I will explain in similar scientific detail as to why human beings shouldn't be able to experience ghostly encounters, even if ghosts do exist, some time later tonight. I gotta head out for now.
