How long has EOS been around?

I'm curious about the history of EOS. Could you tell me how long has EOS been around? I've heard a lot about its potential in the blockchain space, but I'm not quite sure about its longevity. Has it been around for a while, or is it a relatively new project? I'd like to understand its timeline better to assess its maturity and stability. Could you provide me with some insight into its lifespan?
