...I think the job of science is to explain what we observe. We do not observe the origin of life. That life originates is an assumption, currently based on the big bang. But if the universe is eternal (or if the big bang theory has a leak) life never has to originate. It is a big step to get this concept. But without it, we still face the complaint that [panspermia simply moves] the origin-of-life problem over the horizon. I would like to turn the tables. If  darwinists are so sure that life can originate, let them show how. Until then, it's their problem, and life is not required to originate! ...Best regards, Brig
The RNA World is our webpage about origin-of-life theories.

Brig, I have noticed that Vera Rubin is being described by some, including Mr. Hagerty in the WSJ (panspermia website) as having "found evidence" or having "proved" the existence of dark matter. What she really discovered was the flat rotation curves of galaxies suggesting, but in no way giving 'proof' of such matter. To be sure, the flat rotation curves cannot be explained by ordinary Newtonian mechanics based on visible matter, but this does not necessarily force us to conclude that there is unseen matter in place. Rubin would be in agreement with this. Other plausible ways of understanding the flat rotation curves have been proposed--notably the Milgrom theory of modifying Newtonian physics in environments where gravitational accelerations are very small as they are in galaxy rotation. In fact, astronomers are already placing time limits on further unsuccessful searches for the 'dark matter' before dropping the whole idea and rethinking the problem.
