The earliest signs of human existence in North America date back at least 15,000 years, based on archaeological evidence such as stone tools found at sites like Clovis in New Mexico. Some evidence suggests that humans may have arrived even earlier, possibly around 20,000 to 30,000 years ago, as indicated by findings in places like the Bluefish Caves in Canada. These early inhabitants are believed to have migrated from Asia across the Bering Land Bridge during the last Ice Age.

Not yet.When they say not yet, scientists have shown that bacteria on mars or similar planets could be possible, they just haven't found it. In 2004, a team of scientists dug a hole 4000 feet deep into volcanic rock in Hawaii. They found bacteria on living conditions extremely similar to those on mars. Although no bacteria has been found on mars, or anywhere else, we have the proof that it may be able to exist.
