Panspermia question

@OggggO Panspermia is just one theory on the origin of life, and it has credence in some quarters. But you are entitled to your opinion

@usher I’m not commenting on whether or not it’s real, only the possibility of infectious viruses falling from space if it is.

@OggggO How can we ever know what Space contains . It's so enormous that life can arrive from outside the Solar system and contain pathogens of unknown origin. For all we know DNA is abundant in Space or Alien DNA or similar. To close our mind to what is possible or impossible is like closing our mind to future inventions. Sure it's improbable but not impossible. What you need is vision and an open mind. But again I say, your opinion is very valid.

@usher Regardless of what space contains, viruses are highly specialized to their targets. A random virus falling from space would have no better chance of getting into a human cell than your car keys would have of fitting in the fire control lock for a nuclear missile.

@OggggO you are describing Earth virus's. We don't know of how an Alien virus could adapt to the key/locking system of an Alien to Earthling protein. Your imagination will not allow for anything outside of possibility. An Alien virus that has evolved for possibly 19 billon years longer than earth proteins is very improbably, but not impossible. You imagination doesn't allow outside the box. I'm guessing you 're not a sci-fi enthusiast at all. More the pity. you'll have to settle for a Ford instead of a Lamborghini

@usher What you are doing is called the "Arguement from Ignorance" fallcy.

@OggggO oh I understand.. In other words , using my imagination. thanks.

@usher No, you aren't just using your imagination, you are substituting your imagination for facts.

@OggggO What facts??? We know nothing about outer space and it Evolution

@usher We know a shit ton about Earth and life on it. There has yet to be a single lifeform found in outerspace that we didn't put there, nor has any life been found on Earth that doesn't fit within the evolutionary history we have examined. Despite the fact that you think that your personal lack of knowledge means anything is possible, a lot of thought has been put into this. Virus can't just magically "adapt" to fit into new hosts if they don't have access to ones to reproduce in already. They are not going to have some super special biochemistry that lets them overcome the laws of biology just because they came from space. You are confusing magical wishes with scientific speculation. In short, the things you are describing are not merely improbable, they are completely impossible.

@OggggO Perhaps you think the word Improbable Is equivalent to Impossible. You might be one of the middle age thinkers. No problem. The idea of science evolution is probably beyond your imagination. That's not a fault of yours. You imagination has not evolved yet. Why should you worry about that. Not everybody evolves the same at the same rate. Biochemistry on Earth is not necessarily the same for the rest of the universe. You need to expand your imagination to allow new ideas enter your space of thinking. To say improbability is impossible even in Earth scientific terms is 'Unscientific.

@usher Which is exactly why your idea won't work. You literally do not know enough about any of this to realize how little you know. You aren't proposing science, you are proposing magic.

@OggggO If you label it magic then you are part of the middle ages thinking that though Magic was something we don't understand and must be demonic or something. In modern day the magic is known as science.

@usher You still don't get it; I label it "magic" because you are engaging in wishful thinking ungrounded in reality, not because we don't understand it but because you don't know that what you are actually suggesting entails utter ridiculousness. See again my analogy about your car keys fitting the lock for a nuclear missile control panel.

@OggggO Don't be ridiculous, the key/locking mechanism might not only be applied to the human protein viruses. Some scientists believe that Viruses existed since the Earth was quite young and still being bombarded with outer space material. A lot of viruses might have been captured dormant in the early permafrost and rock formations. There are theories viruses might have evolved in early mammals too 200,000 years ago. Your dismissal of where virus came from is not scientific nor valid. Go broaden your mind and get educated.

@OggggO I understand and know a lot about virus and bacteria. I was just helping your to broaden your mind. Your mind is closed so you're not qualified to answer my original question
