There have been more hypotheses that life is not indigenous to our planet Earth, that it did not originate here, but came from outer space. The most well-known hypotheses are “panspermia,” which in our language means “seeds everywhere,” and “cosmozoa.” They differ, mainly, in how life from space came to planet Earth.
First, it was claimed that life from space came via meteorites (the cosmozoa hypothesis), and then that life came to Earth via “pressure of light” (the panspermia hypothesis).
The big and biggest problem with these hypotheses is that they do not answer the question: “Where does life come from?” They, eventually, answer the question “Where does life on Earth come from?”
So, you ask me: “Where does life on Earth come from?” and I say: “It came from space.” And then you ask: “And where does life in space come from?” and I answer: “Well, let them figure that out over there.” That is not a scientific answer.
Meaning, these hypotheses only push or relocate the question of “the origin of life” from Earth to the universe, and clearly, they cover it with an even bigger veil of mystery. The question arises: “How can life overcome the obstacles that govern the cosmic space?” How would it survive the low temperature, cosmic radiation that kills all living things? And even if they could, somehow, let the seeds of life penetrate into meteorites, the question arises: “How would they survive the temperature they experience when rubbing through Earth’s atmosphere?” A meteor, when it enters the atmosphere, heats up, it becomes red-hot, many of them burn up and do not reach Earth’s surface. (We experience this as falling stars.)
And even if we allow that “spores” of life somehow survive the heating (let’s say in the interior) of the meteorite, it is not clear how they would get out of the cooled and hardened meteorite. Moreover, it is hard to believe that any living being, especially the life as we know it on Earth, can withstand or overcome cosmic obstacles such as: the absence of water and air, and even worse – the temperature of absolute zero (-273°C), and cosmic radiation. Finally, none of these hypotheses has proven in any way that life exists in the cosmic vastness. Therefore, it should first be proven, and then, eventually (extremely difficult), it could come, reach Earth, either in the form of spores or something else.
In general, these hypotheses do not solve the question of “the origin of life,” but they only move it further away. People see that it is illogical for life to have arisen abiogenically on planet Earth, and they do not want to believe that God exists, that He is the giver of life, and they expected that these hypotheses would become more and more popular. And these people realize that man is a product of some plan, so they believe that some other intelligent beings planned us. And then others ask them: “What do you think, who created those intelligent beings in space?” Furthermore, “Where is your proof that they exist?”
