like this Earth are few and far between in this part of the physical galaxy.
As a result of the wonderful conditions for "life" here, physical life
forms and whole parts of "other" eco-systems have been brought here by
the "intergalactic red cross" when it was ascertained that the physical
planets they were "living" on were going to be devastated by natural (novas
or supernovas) or contrived circumstances.
This has resulted in the complex cross section of biological entities we see on Earth today, given rise to intellectual thieves like Darwin who come up with their totally mistaken "theories" of how these life forms supposedly "evolved" on Earth. Among examples without enough "time" to have "evolved" in the physical here on Earth, the "honey bee", the bat, etc., with no ancestors, transported here from somewhere else.
