... In support of this theory, is evidence of fossilized metazoans on Mars (Armstrong 2021a;Joseph 2020bJoseph , 2021aSuamanarathna et al. 2021) and evidence that 800 million years ago, Earth (and presumably Mars) were struck by an armada of meteorites, which may have transferred innumerable viruses and other organisms to Earth (Joseph et al. 2020a, Joseph & Duvall, 2021. Even if Martian organisms were not transferred to Earth, the fact that specimens on Mars that resemble stromatolites, algae, fungus, lichens, and metazoan invertebrates are nearly identical to those of Earth (Joseph et al. 2020a,b;Joseph et al. 2021a,c;Armstrong 2021a,b;Elewa 2021Latif et al. 2021Bianciardi 2022); and that based on sequential photos fungi appear to be emerging from the soil, growing larger or smaller or moving to new locations (Joseph et al. 2021b), should be viewed as evidence that similar species evolved, possibly independently, on two worlds; and that the same viral genetic seeds fell upon both planets: repeated viral invasions that led to the metamorphosis of similar forms of life independently and in parallel on two different worlds. ...

... Many scientists have also reported what they believe to be algae, fungi, sponges and corals embedded in meteorites (Birgham 1982;Claus & Nagy, 1961;Nagy et al. 1963a,b;Pflug 1984;Rozanov et al. 2003), some older than this solar system; findings that suggest life may be pervasive throughout this solar system and galaxy (Joseph et al. 2020). If this "genetic seeds of life" scenario is correct, then logically, using Earth and Mars as an example, life would have likely evolved on billions of Earth-like worlds and hundreds of millions of Type I extraterrestrial civilizations would have long ago evolved in this galaxy (Sagan & Angel 1973;Kaku 2007). ...
