Aliens exist (New Age)

Claim

The universe is full of biological life foreign to planet earth.

Response

1. Models that predict extraterrestrial life, and more particularly extraterrestrial intelligent life, are based on unreasonable extrapolation of evolutionary cosmology models. Secular scientists view the universe through the lens of the Copernican Principle (the belief that neither human beings nor our solar system occupies any special place in the universe). They fail to acknowledge the degree of intelligent design in the universe and they do not take into account models that are galactocentric. Such models do not predict extraterrestrial life, intelligent or not, with any reasonable likelihood.
2. Tipler argues that a highly advanced ET civilization would be smart enough to send out von Neumann machines across the universe. These endlessly self-replicating machines could explore every solar system in our galaxy in a "mere" 300 million years. In that case, the various space-exploration programs of the twentieth and twenty-first centuries should certainly have found at least one such machine, and probably several, in our own solar system, or even on our own earth—and no such machine has been found, although multiple out-of-place artifacts of other types have been found even in the deep strata. He then concludes that ET does not exist.
3. SETI has yet to find alien signals, but this can be dismissed by claiming it is only a matter of time.
4. Apart from two unverified UFO sittings and the hype of supposed life being found on Mars, there is no evidence that aliens exist.
