Racket Scheme & SICP is a fun way to start playing, especially if you are into theoretical concepts of CS and programming, like higher order programming and abstraction.
The documentation for Racket is excellent, see e.g.
https://docs.racket-lang.org/quick/index.html
... and many people have created online resources to adapt SICP to Racket, as well as other learning texts. I like Beautiful Racket, e.g.
https://beautifulracket.com/explainer/lists.html
You can use #lang sicp and start playing around with the free online reformatted SICP text here:

I recommend getting a print copy of SICP, though, and working through the examples in a real DrRacket environment on your computer.
IMO, if you end up going deep in the "lispy" direction after playing with Racket, you'll probably be drawn to Clojure as it is the Lisp with the biggest "production use" community at the moment. So long as you can put up with some JVM warts, it, too, will be a good experience.
I have to second this. Racket is absolutely the best place to start. There are great books for beginners, and the documentation is top notch.
it comes with its own editor (Dr. Racket) that does some really helpful things for beginners, like hovering over a variable and seeing lines drawn to where it's being used.
It's not the fastest lisp, but that's ok. It's spectacular for learning and has a huge ecosystem too. My "daily driver" is Chicken Scheme, but i wouldn't recommend it to a beginner. The docs just aren't helpful to newbs (and frequently frustrating to me even though it has one of the better set of docs)
Vim is meh for Lisp & Scheme, and I'm a Vim fan. Emacs is great. If you're a Vim user check out Doom Emacs. It's great for us geeks who love vim but want more power and better lisp support. But... start with Dr. Racket for now.
Others have mentioned the SICP book, and it is good but i wouldn't suggest it as as "how to start with lisp" book. Also, watch the free lectures of the course from MIT. Very good, and make it way easier to work through the book.

It's written in a lisp, runs as lua and supports: Clojure, Fennel, Racket and Janet with a bunch more to come.
