Page "Panspermia" Paragraph 11

* Even if life were to survive the hardships of space, or further, was being created in space, these would be very enduring life forms, as the theory itself proposes, and they would have already visibly populated and altered Venus and Mars as well as other moons in the solar system.

Therefore, the absence of life in Venus, with a somewhat similar composition to Earth's primitive conditions or the absence of life on Mars, given the proposed " resilience " of life in space, damages the panspermia theory, at least based on observations of our own Solar System-the theory suggests that life would be more abundant in the Solar system.
