There were multiple migrations out of Africa

"Homo erectus migrated from out of Africa via the Levantine corridor and Horn of Africa to Eurasia during the Early Pleistocene, possibly as a result of the operation of the Saharan pump, around 1.9 million years ago, and dispersed throughout most of the Old World, reaching as far as Southeast Asia. The date of original dispersal beyond Africa virtually coincides with the appearance of Homo ergaster in the fossil record, and about half a million years after the appearance of the Homo genus itself and the first stone tools of the Oldowan industry. Key sites for this early migration out of Africa are Riwat in Pakistan (~2 Ma?[1]), Ubeidiya in the Levant (1.5 Ma) and Dmanisi in the Caucasus (1.81 0.03 Ma, p = 0.05[2]).

China was populated as early as 1.66 Mya based on stone artifacts found in the Nihewan Basin.[3] The archaeological site of Xihoudu (西侯渡) in Shanxi Province is the earliest recorded use of fire by Homo erectus, which is dated 1.27 million years ago.[4]

Southeast Asia (Java) was reached about 1.7 million years ago (Meganthropus). Western Europe was first populated around 1.2 million years ago (Atapuerca).[5]

Robert G. Bednarik has suggested that Homo erectus may have built rafts and sailed oceans, a theory that has raised some controversy.[6]

The expansion of H. erectus was followed by the arrival of H. antecessor in Europe around 800,000 years ago, which was in turn followed by migration from Africa to Europe of H. heidelbergensis, the likely ancestor of both modern humans and Neanderthals, around 600,000 years ago.[7]

Homo sapiens seem to have appeared in East Africa around 200,000 years ago."

Although this text describes just a few distinct species migrating out of Africa, I would expect the migration to have been continuous. That means hominids were continuously migrating out of Africa at least 1.9 million years ago, with evidence of them settling in China 1.66 million years ago. This is 1.4 million years before homo sapiens even existed in Africa. Given this widespread, pan-Asian migration, and the enormous span of time available to them, it is very hard for me to believe that they (perhaps many multiple varieties of hominid) did not also find their way across the land bridge (or along the coast) and into the Americas. Very hard to believe indeed, even if no evidence has been found.
