By that argument your mouth is a continuation of your asshole... No offense.
I mean… yeah
Some people haven't realized almost all animals are just tubes with various fancy shit glued on.
Edit: including humans
Or put biologically, virtually all fauna are just various advanced forms of flatworm.
IIRC humans have 7 holes topologically (assuming both vsauce and my memory are correct). I'm not sure how many a flatworm would have, but I bet you could group animals by number of holes topologically, which might be interesting.
Flatworms have a single opening that leads to a branching cavity (an incomplete digestive system). This means that the single opening is for both ingesting nutrients and expelling waste. While your mouth may be attached to your anus via the alimentary canal, I think it beats the hell out of having one multi-purpose opening, imho.
Right, technically a human only has 1 hole for ingesting nutrients and expelling waste as well though, assuming you are talking about the mouth and anus. Does a flatworm have any other through holes though e.g. nostrils or tear ducts? I have no idea what the biology of a flatworm is haha.
No, gas exchange is by simple diffusion across the skin and gut. No ears or eyes per se, just some photosensitive cells in slight depressions on the head. Planaria are pretty simple as far as animals go.
Two ears, mouth/anus/nostrils, urethra, optionally vagina. That's 5...what else, eye sockets?
I guess we all are talking out of our asses, then...
Indeed, and when you kiss someone you are making one big hole connected by two assholes.

For normal people asshole would be continuation from mouth, but I don't judge. You do you!
I assume that's how OP's debate of how many holes a human had ended up being about straws: someone argued that the mouth and the anus are just one hole
Given the amount of people I know who are always full of shit, I'd buy that
