Hidden assumptions (Score 1)

There are many hidden assumptions here. ET is interested in talking with us ET is interested in Planets ET is carbon based. Is it possible we a just too dumb or dangerous to bother with. Do we need to wait until we genetically engineer ourselves? ET may have had bad experiences with other species and decided to hide. His com system may be point to point so as not to give away their existance. Once ET can create space habitats why would they be interested in planets. Carbon is good for encoding information in long strings and water is a carbon solvent. There are 46 relatively complex chromosomes. Is it possible to produce life with thousands of small chromosomes. Are there liquids that act as solvents for these chemical?
