Yup, number 1 of course. Scientists aren't totally stupid, they've done the research and whilst there are big gaps the evidence is consistent with their theories. Otherwise, why would they be saying there's not a smidgen of evidence for little green men?
Are you ready to answer the question now?
Yes I'm ready. If my scenario 1 is what you have in mind, then no this is not evidence for ET.
I must say that, if you believe that your moon scenario has any resemblence to life on earth, you are labouring under many misconceptions. May I ask your view of evolution? Do you accept the idea of common descent? Have you looked into the genetic/DNA evidence for common descent?
In your replies to Caedes you (and he) speak of a human-engineered living thing made of organic molecules. You claim that if you looked at such a thing that one would not be able to distinguish the humanly created from the naturally evolved. I must say here that you are flat wrong about this. When looking at biological organisms which have evolved, we can see the history of changes in the anatomy and genetic make up (genetic drift, vestigial organs ...). If a human created a living biological thing, we could not help but leave our fingerprints all over it. Even if you care to imagine some distant future where we have the resources at hand to create a biological organism with its own fake backstory to make it look like it evolved, this will not help your case. Does the God you imagine create life in such a way as to remove any trace of his hand in his handiwork? Does he then abandon his handiwork to the whims of time and forget all about it? Why bother with a God like that.
I've had some family stuff to sort out, so I've been away from home for a couple of days. It's nice to be missed tho'.
