How do you think people learned to draw before AI?

Look up tutorials online. DeviantART is a shithole nowadays but it has a massive repository of art tutorials on damn near every subject matter. You can also find tutorials on YouTube or via your search engine of choice.

Go to bookstores and libraries, if there's one near your house. There's a wealth of art instruction books available to you.

And just draw, man. Draw the stuff that's around you. Still life, a tree, a squirrel, your friend, whatever. You learn best by doing, when it comes to art.

And finally, stop using AI, period. AI steals artists work and takes jobs away, not to mention the heinous environmental impact.

There's really no "easy" way to learn how to be an artist besides what I've suggested above. Like with any skill, it takes a lot of practice and a lot of time.
