Just looking for other answers to this.
How do you know that you know anything? How do you know you can rely on your senses? (As in: I know the rock exists because I can see the rock. How do you know you can see it?)
If knowledge is reliant upon our senses and reasoning (which it is), and we can't know for sure that our senses are reasoning are valid, then how can we know anything?
So is all knowledge based on faith?
If all knowledge is based on faith, then is science reliable?
If all knowledge is based on faith, then what about ACTUAL faith? Why is it so illogical?
Solipsism vs Nihilism
Solipsism claims that we know our own mind exists, where Nihilism claims we don't know that anything exists.
Your thoughts?

I do not think, we can guarantee our senses to sense reality. But what distinguishes science from faith to me, is ultimately a principle known as Occam's Razor.
Essentially, it says: When trying to find an explanation for something, prefer the explanation that requires fewer assumptions.
So, in regards to our senses sensing things, there's two possible explanations:
And with 2), you have to make the assumption that your entire perception is somehow being imagined/simulated and you presumably have some other form of existence, too. Because well, if you wouldn't exist, why would you be imagining things?
So, on the basis of that, 1) just seems less far-fetched. You're just perceiving what's real.
If we ever find evidence that this isn't actually the case, then of course, we should change our minds, but until then, there's no point in seriously considering 2).
It can be argued that Occam's Razor isn't inherently guaranteed either. My preference for it certainly comes from what I have perceived.
But well, if there's a religion that assumes everything exists in all places all the time, and that every time I lift my finger when typing, there's an invisible coffee table there with Santa, the tooth fairy, Big Foot and a pink space unicorn, I would be down for that religion.
