It cannot replace the theory of evolution, since the 'Intelligence' behind must have stemmed from something as well.
It can however still be a useful thought. It is an often heard opinion that the biological ecosystem we have on earth is not only improbable but also very difficult to explain using our current mainstream evolution theory alone. There just hasn't been enough time for Earth to develope like this without intervention, it is argued.
What if this is true? There certainly exists things on Earth which seem quite weird indeed with the perspective of Darwinism alone. An example would be parts of our basic cell structure where the system consists of parts which alone are completely useless and should have been erased by evolution before coming to terms. This strange 'jump' which must have happened, where all the parts mutated into place at the same time, is odd. A clue perhaps that something is going on.
If so, then this theory could help explain it. If there really was an invisible alien hand meddling with the evolution of this planet, it could explain the oddities and the relatively short timespan it all happened in. This intelligence in turn could have come from a planet or other habitable place were they were given enough time for their own evolution to have happened naturally.
I like the thought. Why do you think we began hearing about aliens performing genetic experimentation on humans after 1950 only? Perhaps because they have been here all along but we only now attained the technological capability to register them.
Intelligent Design.
