If souls don't exist, then there is no reason to try to develop a connection to Dark Matter.
If I said I think pixie dust is actually neutrinos, it would be non-sensical, since I've just made up pixie dust.
So, my first step would have to be to show that there is a problem here to solve, which is: nevermind neutrinos, does pixie dust even exist in the first place?
So, as always happens, to discuss the details of souls, you'd have to first show that souls even exist.
You statement is not valid. by saying the soul does not exist.
Question : does Dark matter exist ? Is Dark matter part of the universe, is life part of the universe ?
Is the universe composed of 85 % of Dark matter, Here is definite number given by science . Do you accept as is is true ?
