Yeah, some people can't do things on their own or have the inner strength and emotional fortitude to deal with the abject misery that comes with existence, so they need an imaginary friend to help them out a little.
For some others, I think it really comes down to not being able to wrap their heads around the notion, at some point, I will no longer be, so they have to believe in God...the afterlife...etc...because they are mentally weak and don't have the psychological fortitude to admit their fundamental worthlessness relative to a cosmic scale (I'm worthless too, ftr) and impermanence to be the most likely of all possible cases. If nothing else, we have concrete evidence that things die, but no evidence that those things exist somewhere else after that. Accept it. Quit being weak.
As far as, "Turning things around," I guess the ends justify the means if they have no other way of getting themselves there. The unfortunate aspect of it is that it tends to be those people who are the most vocal about their religious views and trying to get others to join up with them. Look, I get it, you (general you, nobody specifically) listen to the things that your imaginary friend tells you to do and it has improved your life. Fucking fantastic. I'm happy for you, truly.
I don't want to hear about it, though. I don't need an imaginary friend. I don't need any sort of inner peace that is, most likely, fundamentally false. You live your lie because the most likely truth is too much for you to bear; that's fine, but you do not need to try to convince others to join you in your pathetic charade.
I definitely agree with the last quoted paragraph; 100%. That's just the tendency towards tribalism and trying to build up group numbers with a single-minded focus so that all possible threats can be overcome. IOW--weak, illogical and outdated animalistic behaviors that are a carry over from a time that they were necessary for survival.
Evolve your thinking.
The most likely case is we die and that's just it. There is no inherent meaning to life and any meaning that life has is simply whatever subjective meaning we can find in it, which will vary from person to person.
We have evidence that the Universe is rapidly expanding, as objects get further and further from one another, we will eventually (trillions^ of years) reach a temperature of near absolute zero and all entropy will have failed. There will be no two extant objects physically close enough to even gravitationally be attracted to one another.
All life will end and, effectively, the only thing left will be nothing.
Of course, all of us here will be nothing long before that.
Embrace the peace that comes from eventual non-existence. Who would ever want to exist for eternity anyway? Sounds absolutely dreadful.
