No idea? Really?

You’re an intelligent mammal, your biological makeup encoded in DNA. So are all other people, who largely share that same DNA. You’re conscious. It’s not a big leap to conclude that so are other people, too.

This kind of solipsistic sophistry is not productive. It might be entertaining if you’re contemplating the underpinnings of epistemology for the first time in your life, but it’s not an honest contribution to the debate.

You might as well claim that you have no idea if gravity will be in effect tomorrow.
