How is it anything exists at all? as opposed to nothing exists?
materialism has no valid answers
it just presupposes its own conclusions
Discussion
1. Not every question has an answer we can comprehend (see quantum physics). Some answers might be comprehendable but the information we'd need to answer the question is inaccessible (like "what was the population of a given lat/long coordinate in the year 1345?")
2. Why do I need to answer that question in order to answer other questions? Assuming some priors and is always a necessary limitation. If you learn new stuff about those assumptions or find new information that indicates the priors are imperfect (as they likely are) you update a bit.
"The best you can do" is a fundamental aspect of world.
“assuming some priors”
yeah, and and not all assumptions are valid
“if i assumed all of reality was made of cheese” you wouldn’t take it serious.
it’s demonstrabley wrong. it doesn’t have an answer to account for everything not cheese
it’s the same as assuming all of reality is just matter.
I wouldn't take that assumption seriously because it immediate conflicts with all sorts of observations and experiment and doesn't explain any new unexplained phenomena.
Your argument here rests on the same processes that you are trying to say are useless.
