Eli5 how did early primates/hominids successfully migrate to anywhere America?

After some brief research, it appears the most common consensus is; “primitive monkeys floated across the ocean on naturally constructed rafts made of vegetation and earth”

this is somewhat hard for me to believe considering the substantial intellect it would require to make a working raft and most vegetation would probably sink/ begin to rot after such prolonged submersion 
Even modern-day humans had some trouble crossing the entire ocean on a gargantuan 300 ton vessel.
So, how is it archaic primates reached an entirely new continent well over a thousand miles away? How could they have gone so far without starving, dying of thirst, or the succumbing to the elements?

If the raft theory is consensually believed to be true, is there any physical evidence/artifacts still remaining to support the theory?

No other hominid primates have ever migrated to North or South America; not Neanderthal, not Homo Erectus, only Homo Sapiens.
"New World" primates are only distantly related to humans, unlike chimps and the other great apes which share a common ancestor with us about 5 million years ago.
