The problem is that you are just transferring the question of abiogenesis from earth to some unknown planet. You are not resolving the serious scientific problems with such a theory at all. Also such an assumption is not science. Science deals with what can be tested, such an assumption is untestable.
Who says that it has to be answered here on earth? As I 've mentioned, it is quite clear that the ID math model of life origins on earth says that there isn't enough time for such complexity to have come about by naturalistic processes. This ID model isn't the only such model or speculation from those out of the evolutionary field itself. It is simply a recognition of a very REAL problem that's been known in the evolution camp for some time. The mathmaticians simply put numbers to an already known problem with the EvoTheory itself. It IS part of the scientific process to propose solutions to KNOWN PROBLEMS with any theory. The time/complexity problem has been a KNOWN PROBLEM with EvoTheory WITHIN ITS OWN FIELD for at least three decades.
The proposal that earth was "seeded" by intelligent life from outside our system says that life originated elsewhere. Once we get to this particular ELSEWHERE, it will probably be quite clear in that DIFFERENT SYSTEM how life came about.
There IS CONSIDERABLE data on EXTRA-TERRESTRIAL LIFE. There are renowned projects in the scientific community SEARCHING FOR extra-terrestrial life. They are funded with serious dollars by institutions of higher learning and by dollars from the government itself. There are RESPONSIBLE sightings of objects and phenomena that are unexplained but which are clearly indicative of ETI.
Do you believe that this vast universe contains only OUR intelligent life form? Saying "yes" to that question is as religious a statement as to say that the earth was created in 6 days.
If we have to wait to get the answers in perspective because the data doesn't fit here, then so be it. I'm an adult. I can handle it. Everything doesn't have to start and end with earth and man.
