So what makes us specific? First of all, we were created evolutionarily in several stages. This is not a unique case in our universe, but there are few such civilizations. At different times, the genes of people from other planets and dimensions were mixed into the genome of prehistoric humans.
Here you might object that our genome is exceptionally similar to the genomes of other primates and even to the genomes of other mammals, and that if the genomes of aliens had been mixed into our genome, the difference would be greater. To this one can reply that our genomes (those of humans and primates) are traditionally compared in those parts of them that scientists understand - that is, in the DNA sequences that code for proteins and are not burdened by repetitive sequences. The remainder of the genomic sequence, which scientists do not understand - that is, about 95% of the genome, conventionally called junk - is usually excluded from analysis.
It is precisely in this 95% of the genome, not yet understood by earthly scientists, that the differences between humans and primates are sufficient to allow for the presence there of the genes of extraterrestrial humans. And, one may surmise, it is precisely the repetitive DNA sequences that are responsible for the connection between the physical and the non-physical world, and, most likely, it is in them that the functions of thought are encoded.
