The simple truth is that you will only find out when you can move sufficiently far away from it yourself to be able to observe it yourself.
Until then it's pointless speculation, because you have to believe what someone else says, so you'll believe but you won't know.
But aside from anything else, it's a typical human complete-waste-of-time, leading to mental frustration and dissatisfaction, since you are not connecting with anything deeper within yourself (which is the real purpose of life).
There are far more worthwhile things a human can expend their energy on.
eg meditation, or practising gratitude for the things you have.
Those things have the potential to lead to somewhere more real within.....
