What is the best language to hack in, and can somebody make a good course in hacking because I want a career in cybersecurity
Hacking isn't really about knowing a language. Sure, you need programming knowledge, and if you're trying to hack with, say, an SQL Injection then you would of course need knowledge of SQL. Cybersecurity is quite a broad term - I think what you're thinking of is ethical hacking.
A great place to learn about cybersecurity and becoming an analyst is cyberdiscovery. Try their course next year, it'll show you cybersecurity is for you. Good luck!
