Do humans have alien DNA in them?

Answer 1

Stephen Hawing told SETI that sending out signals was a mistake because our history shows what happens to less evolved cultures when the meet other advanced cultures, just ask the Mayans and the American Indians…see I base my response off of historical facts, and u?

Answer 2

If you are referring to life from other planets, the answer is no. Modern experiments have shown that the chemical building blocks for life can be made naturally here on Earth. The prominent view is that the first forms of life, simple-celled organisms, were derived from these chemicals billions of years ago. These organisms gave rise to fish, amphibians, reptiles, birds, and mammals. Humans are descended from mammalian primates. Therefore, all life on earth is derived from the same earthly DNA. It is important to note that meteorites have been found to contain the same chemical building blocks (see the linked articles below for more info). So it is possible that the simple-celled organisms could have been derived from chemicals from beyond the earth. But this is still not the same as extraterrestrial life intentionally or unintentionally mixing their DNA with early life on Earth or, at the latest, early human species.

Humans do, however, have foreign "hitchhikers" in our DNA. Mitochondrial DNA (that passed from a mother to her children) is comprised of two different DNA lineages. Evidence suggests that an early eukaryotic cell absorbed bacteria from the aquatic environment. The resulting hybrid serves the purpose of converting food into usable energy in the cells of humans and animal life.

Answer 3

There is no evidence whatsoever that aliens "made" humans, or that there are any aliens, for that matter.

Answer 4

There is no scientific evidence to suggest that humans have alien DNA in them. All human DNA can be traced back to common ancestors on Earth.
