The limits of science

I found this talking about the limitations we have when sharing information, though I think it’s a jab at science.

That at the end of the day all we have to navigate the world is our senses and cognitive abilities, and the only way to communicate to each other is through language which is flawed in itself. I think it’s trying to argue for the validity of multiple versions of cosmology or whatever.

But isn’t he point of science that we have other people to verify and test things because our perceptions aren’t 100%?
