Hi there,
I'm relatively a newbie in bitcoin and entire crypto technology, Although I have read about a lot of things on how it works and its security,  but so far, the more I learnt has brought about even bigger questions to which I seek answers to.

My Question(s) goes thus: is there any chance of someone generating a bitcoin address that has been generated or belong to someone ? A dumb question as it would seem, but my reason for asking is that, having read that bitcoin addresses are generated in respect to a specific private key and for the fact that an address could be generated offline, also that there is no central database that would be crosschecked by the address generator to know if the address is already generated by someone.
So, even if it is very unlikely is there an iota of chance that it could happen, I mean a greater than zero chance ? If No, please enlightening me on why and how.
