Probably
The truth is out there, and Kendrick Lamar has seen it.
In an interview with radio shock-jock Howard Stern, Kendrick revealed that he was probably abducted by aliens as a kid but nobody believed him.

"It's just something I can't really describe, because it just sounds like,'Okay, you just seen a dart go past. That s--t don't make sense'. Nobody believed me then and they don't believe me now". Honestly, this leaves us with more questions than it answers. A dart?
Kendrick goes on to say 'That's probably why I'm doing music right now. Who knows. They probably gave me the energy.'. I'm into this. I want to believe that there are aliens going around (dart-shaped) who visit musicians as children and give them creative energy, it would really help explain the existence of David Bowie and Prince.

Just as an aside, NASA are holding a press conference on Thursday at 1pm EST to share news about a new discovery found by the Kepler space telescope. The telescope has been looking for alien life for eight years so who knows... maybe Kendrick was right
