Why should I get into alchemy?

First off, I’m not intending this to be an insult to anyone of the craft. But my question is genuine, why should I get into alchemy when chemistry and quantum physics have replaced it? My understanding is that alchemy was the predecessor to chemistry, before we fully understood how chemical changes work. It assumes that all matter is divided between the 4 main elements and some combination of them, no? Fire, earth, wind, and water if I’m not mistaken. But isn’t that just outdated science that’s inherently wrong? I mean now we know that every substance is made of molecules, and every molecule is made of atoms, so isn’t alchemy just an outdated practice? I kind of understand that there’s a philosophy around it, and that’s only reason I can see as to why people would still practice it even after it was proven to not be able to do what it was claimed to have been able to do (transmute lame metals into precious metals). Thanks in advance for your understanding and explanation!
