The problem with philosophy is that it is all theoretical and can never be proven. If it could, it would be science. You are literally just reading an opinion of someone and using that to justify everything. And if there truly was someone that was correct we wouldn't have philosophy in the first place and just follow that instead.
Of course, this is a gross simplification, if you want more you're gonna have to join me on twitch for that one :P but my point is philosophy should not actually be taken seriously outside if just learning about people's mindsets. If you truly wish to gain meaning, do what you believe in or probably go into some other field where you can actually prove things like chemistry or physics. But what do I know I merely do politics.
Everything you just said is by your own axiom a bullshit opinion. Where does science say that the totality of reality can be uncovered by the scientific method? Can you "prove" empirically that your own method can uncover universal truths? You're gonna "prove" what everything is by the scientific method? Stop listening to pop "scientists" and parroting this retarded argument that's been refuted so many times.
