The reason I am citing phenomena such as multiverses etc....is that these are just possibilities that are acknowledged by science. That is all that is required for NDE's and ghosts etc. also.
That's not 'all that's required' - multiverses are considered viable because there are models that predict the existence, and now we're looking for evidence. With ghosts we have claims of existence but not the reliable evidence to support it.
They cannot be regarded as imagination because they happen regularly across the world, across different groups and have many consistent details. Dismissing them as imagination is foolish.
Nobody is blanket dismissing them as imagination, in at least some of these instances there are very real experiences; what's being doubted is whether the claims of the source of the experience are valid. They experienced 'something', but it seems unlikely that it was a disembodied spirit.
As to what they may be...we don't know.
There we go, that wasn't so hard, was it.
So what if we don't know what they are or are unable to provide evidence of them or are unable to investigate them?
So we keep investigating, we don't just go 'let's assume they're ghosts'.
They are real phenomena that real, honest and intelligent people experience, that is all.
That's not all, that's the start - phenomena are the start of the journey, now you have to try to come up with an explanation, consider what the implications of that explanation might be and then test those implications to validate the idea.
Denying them or calling them hoaxes doesn't help.
We're questioning your explanation, not the reality of people's experience.
Lumping them together with religious beliefs and mythology is also a mistake.
Why? You have claims without sufficient evidence, and the reinforcement of prior presumption is used to justify the claim, sounds like it shares at least some traits with mythology to me.
Accepting NDE's and ghosts as real is not the same as accepting the six day creation or Adam & Eve or stories of different gods.
Six day creation and Adam and Eve no, I'll grant, but belief in different gods... how is the claim 'god did it' differentiatable from 'a ghost did it'? Or, to put it differently, if I have an experience and two different people give me those two explanations, how do I test between the two?
Secular but exotic phenomena exist and they have to be accepted as real regardless of our ignorance of them
Exotic is not the same as supernatural, though.
Atheism should not be habitual denial of anything that is not yet a part of mainstream science.
This isn't about atheism or theism - there will be people of faith who do believe in ghosts and people of faith who don't, and the same for non-believers. That I'm an atheist doesn't inform this opinion, rather my atheism and my 'a-ghostism' come from a similar place: we have phenomena, but there isn't sufficient rigorous evidence derived from or about those phenomena to support the claims being made.
