How can absolutely anyone take "technical analysis" seriously - especially the people doing it?

I just read this in another thread. I changed the coin name and numbers, because it's really not about that specific case, but it always looks somewhat like this:

We can expect XXX to set up a higher high above $144.6, confirming the start of a recovery rally. This will suggest that XXX is ready to retest the next resistance level at $160.6. Clearing this level will put $174.9 in its path. If XXX retests this level, the run-up will constitute a 27% ascent from the current position."

People know that coin prices only depend on what people buy and sell and that there is no "science" behind predicting those numbers, right? How could anyone get to these numbers and think "oh yeah, those precise numbers definititely look right!"? It's no better than guessing, stop falling for it.
