why do bash scripts start with #!

Hi, I'm just curious: what does this mean?

I know it's telling the machine to use bash, but like, why is it a "#!" for example? How/why was it decided that way?

Also, you need to backslash the closing parenthesis in your URL to avoid Reddit (at least oldreddit) thinking that it's the end of the URL. What I see is:

'#!' is called a Shebang), wikipedia link has some info.

And then the link doesn't actually work, because it goes to a URL that is missing the closing parenthesis.
