Yeah, I know... just throw this in the non supportive pile of what we already knew.

No A DIM you are once again making the wrong connections. As has just been stated all this evidence proves is the the materials life needed to get going on earth are common in space and that includes some organic chemicals as well as inorganic ones. The only conclusion one can draw from this is that elsewhere in our Galaxy there will have been many other planets which were bombarded with these Amino acids. Many of those planets will have been totally unsuited to the emergence of any form of life which we would understand as Life. Some of those planets (though we have as yet no way of knowing how many, if any) may have have had similar masses, temperature ranges and water content to earth. While that would have at least meant that they were possible candidates for the emergence of life the Jury is still out as to whether any life actually emerged there.
All we can say is the raw materials for life are common in space. Therefore given the right conditions life might have a better chance of getting started. Unfortunately the only place we presently know of that had/has the right condidtions for that to happen is this lump of rock we are living on. That is not evidence of Panspermia. For all we know now earth still could be the only place within 500 light years where everything happened to come together.
Maybe as planet finding astronomy improves over the next 100 years we will be able to fill in some more gaps in that knowledge but it is at this time reckless to make assumptions about such planets without the hard evidence to back it up.
