or I should say "within the realm of current technology" ( that's traveling at 200,000 mph with ion drive starship )

a multi-generation ship beyond the creative thoughts of mankind right now.

Guess we need warp drive or wormholes or whatever.

120 light years at 186,000 mps x 3600 sec/hour x 24 hours per day x 365 day per year = 703 million million miles.

Current theoretical speed of ion drives... 200,000 mph...

we need something 100 x faster than ion drives just to put this in the realm of the possible. 1000 x faster to make it a "sure maybe we can do it" and 10,000 times faster for the "who wants to volunteer to leave and return in like 80 years?"
