DNA IS composed of nucleotides. A nucleotide consists of a phosphate group, a five-carbon sugar and a nitrogenous base bonded together. The combination that goes to make up DNA therefore represents chemical that are endemic to this planet in proportions that are normal to this planet. You may have heard that because of our close relation to chimpanzees our DNA IS 99% identical to theirs and yet human chimpanzee hybrids are not viable, what percentage would you expect us to have in common with a creature that evolved on a different planet ?.
Every creature on this planet features this combination of chemicals in its DNA, this is because the DNA evolved here, in effect it represents a certificate of earthliness. This is what led Carl Sagan to comment that a human is more likely to mate with a petunia than an alien.
whoever asked you how I know this obviously doesn't have the genetic understanding to answer their own question
so perhaps you should link them to the easily understood wiki page on the starchild skull which has recently been updated to include this

perhaps you could also link us to the forum youve been posting my comments at so I can answer the question myself

.DNA testing in 1999 at BOLD, a forensic DNA lab in Vancouver, British Columbia found standard X and Y chromosomes in two samples taken from the skull, "conclusive evidence that the child was not only human (and male), but both of his parents must have been human as well, for each must have contributed one of the human sex chromosomes".[1] Further DNA testing at Trace Genetics, which unlike BOLD specializes in extracting DNA from ancient samples, in 2003 recovered mitochondrial DNA from both skulls. The child belongs to haplogroup C, while the adult female belongs to haplogroup A. Both haplotypes are characteristic Native American haplogroups, but the different haplogroup for each skull indicates that the adult female was not the child's mother. Trace Genetics was not able to recover useful lengths of nuclear DNA or Y-chromosomal DNA for further testing
