alsoThere is the capability of recovering very old DNA. It's extremely difficult and costly but possible. It is possible to obtain both ancient DNA sequences and radiocarbon dates from the same sample material by destructive methods.
The complete mitochondrial genome from a 300,000- to 400,000-year-old sliver of human bone found in Spain's Atapuerca Mountains has been now sequenced.
To their surprise, this proto-Neandertal yielded ancestral Denisovan DNA.
The oldest DNA sequenced is 2.4 Million years old...non-human permafrost preserved in Greenland.

For this method to work, they would have to eat stuff from earth and be here for long enough time for all of their body cells to be replaced (7 years in a human). Or they would have to come from an environment were the C14/C ratio is exactly as earths...also
scientists from the university of Mexico used radiocarbon dating and came to the conclusion they are a thousand years old?
Radiocarbon dating works because radioactive C14 is created in EARTHS atmosphere at a consant rate. EARTH plants take C14 up during photosynthesis, animals by eating plants/other animals. Hence, the ratio of C14 to normal C is the same in the atmosphere as in living organisms. Once an organism dies it doesn't take up any more C14, C14 starts to decay at constant halftime (5730±30 years), and the C14/C ratio shifts.
Key here is this is specific to earths atmosphere the cosmic radiation (mainly from the sun). Using this method on EXTRAterrestrials would be beyond stupid

Hi man.., By the way, could you tell me in a nutshell whether this DNA report could be correct or incorrect? Could it be an alien or a piece of dried fish eaten by the Incas?There is the capability of recovering very old DNA. It's extremely difficult and costly but possible.

There's no report... Only a reference to a report. Even a banana has 60% of our DNA.Hi man.., By the way, could you tell me in a nutshell whether this DNA report could be correct or incorrect? Could it be an alien or a piece of dried fish eaten by the Incas?
awesome knowledge machanFor this method to work, they would have to eat stuff from earth and be here for long enough time for all of their body cells to be replaced (7 years in a human). Or they would have to come from an environment were the C14/C ratio is exactly as earths...
True...
There are other factors too. The C14 isn't created at a constant rate. The Solar activity (Cosmic Rays) and also because of the above ground nuclear testing the Earth's atmospheric radiocarbon levels almost doubled from 1955 to 1963. Since then it has dropped back to the previous levels.
However there are established methods for applying a correction using a calibration technique. This is where the calBP unit is used.
For recent human bodies it's noted that for teeth formed after 1965, enamel radiocarbon content predicted year of birth within 1.5 years.
Also modern radio carbon dating uses a different technique - AMS - Accelerator Mass Spectrometry which is an ultra-sensitive analytical technique based on the use of an ion accelerator as a powerful mass spectrometer. The equipment itself is expensive but even a small sample of bone (less than 1 gram) is quite sufficient.
