Francis Crick

Francis Crick was one of the discoverers of the structure of the DNA molecule in 1953.

Life from Mars
In 1973, Crick proposed a theory of directed panspermia, suggesting that life on earth could have originated from DNA "seeds" projected into space by an extraterrestrial civilisation. This is in contrast with normal panspermia (undirected) where life merely has its origins in space (a very broad assertion, with a range of interesting ramifications), but no intelligent entities were behind it. Because of this, he has sometimes been cited by the intelligent design movement as an example of a secular and atheist proponent of intelligent design. However, Crick never asserted that directed panspermia was a fact, just an interesting possibility, and seems to have later discarded the idea.

Furthermore, the theory of directed panspermia relates to the origins of life — something about which evolution says absolutely nothing. Consequently, even if correct, it would not be incompatible with evolution and does not mandate an "intelligent design" for humans or other advanced organisms.

Quote mine
Being a well-famous biologist and one of the best-known proponents of panspermia, Crick is frequently quote-mined by creationists. In Life Itself, Its Origin and Nature, he stated:

However, the ellipsis there marks the start of a less frequently quoted section (and often creationists citing this comment will leave out the ellipsis to try and punctuate it at "miracle"). Crick continues, lest he be accused of being a total idiot rather than a fairly competent scientist:

In short, Crick acknowledges the difficulties in really figuring out the origin of life but doesn't suggest a literal miracle.
