First related to what was mentioned above, entanglement doesn't allow for instantaneous communication because it doesn't allow for communication at all since there is nothing transmitted, i.e. no energy or anything is sent from one particle to the other.
Secondly you can't really send them human genetic information to build a human because you can't do anything with the genome without the complex biochemical environment of an already living human cell. Easy for us with them already present, but not for the aliens. Like having a programming language source without the compiler if the compiler were a physical machine.
