Reincarnation

I wanted to share my knowledge with my friend Darelle on this subject. I have always done so. The thing is that now I do not have the means to do so.
Just yesterday; I learned the explanation given to reincarnation by beings from other worlds. They have also spoken of the fact that they themselves have had something similar to environmental phenomena due to climate change, and that many of them have had to die as a consequence of environmental catastrophes. To settle this issue; they have said that this is due to the action of man. The fact is that they said it half a century ago.
I wanted to open this debate because it is something that we have talked about. And the program has left open the question of whether changes are perceived for our humanity. In the medium or long term!? It cannot be specified. How these changes will occur has not been made clear either due to censorship issues. Because the protagonists have not said everything they know on purpose.
The question of reincarnation is also of great interest to us. The Aliens have ruled out that it is not about reincarnation in another body... But it is only a part of us that can take a different form than usual. And what it could be about is, for example, when someone decides to lie or is invaded by envy. The Aliens have said that this is typical of our humanity since the inner being is made up of several identities - I would call it. Among these identities, a part is recognized that they call 'The Deep' and that according to what has been said, it could be about God. Leaving aside theories because they are not for our world; it is important that reincarnation continues to have its sense of being in harmony with the environment. But in this case, it will be this harmony with our being. My theory is the usual fight against the devil because there are no more entities than these two.
