Hello and welcome!
I, like others here, can't understand why someone would start vaping (with nic, anyway) after never having a cigarette but it's the same as I can't really understand why someone would start smoking cigarettes. I'm fairly young but started smoking 15 years ago and honestly, I can't understand why I did then. I'm sure a lot of (ex) smokers, if asked to look back, can't understand why they started. Peer pressure for younger people, work or social stresses for others etc sure, but when you add up the money, the health issues, the stress that smoking brings itself, it's hard to understand why someone would make that choice. But we, and many others, did. And still do. It's all being informed, or choosing to ignore it.
In short, welcome to vaping and congratulations on picking up the obviously better way of using nicotine!
