I don't think someone can generate new address that actually used by another user before.
The chance getting this is very very small
The length of private key is make sure there are so many bitcoin address out there

ha ha ha, why you use this smiley? ->
it seems you have the wish, to generate (brute force) a address of your choice somehow ^^ right?
We just don't have the technology to do so. The amount of time and power required to brute force this is hard to say. It would take who knows how many years it could be after most of us are dead.
Maybe if a future far far away... but not going to happen anytime soon.
haha, i wrote this already few posts before

I think it is not possible during my lifetime, even if with computer which are 1000 times faster than today.

but my question now is, HOW TO CALCULATE THE REQUIRED TIME
lets assume i'm able to calculate private keys with ~33.33 Mkey/s
