What exactly is your problem Rob?
If there is a possible natural explanation for the signal then it cannot be considered as the product of intelligence.
I said
Too funny. That is exactly how they test signals. To be considered other than natural there must be no way that it could be natural. If there is a natural explanation then it cannot be considered indication of intelligence.
and
It would have to be a code that could not be explained by any natural process. Even then, it would only be accepted as possibly sent by intelligence.
Sorry but those two statements seem consistent.
If there is a possible natural explanation then that is what is accepted.
If there is "NO possible natural cause" then it can be classified as "possibly the result of intelligence."
Possibly.
If we cannot explain a signal through natural causes then it goes in the "Unknown cause" folder, not into the "Intelligent caused folder."
To move towards the Intelligent caused folder you would need additional confirmation. For example, a continuing conversation would help but still not be conclusive.
That is how knowledge and science work Rob.
Your incredulity is simply nothing but incredulity.
And it still has nothing to do with the thread or the topic which, in case you missed it, is "Converting raw energy into biological energy".
