That's not to say he stole an idea of course!!

Dan O'Bannon, who wrote the film, has said "I didn't steal Alien from anybody. I stole it from everybody!"  He cites a number of stories and films from the 50s and 60s, but doesn't mention Doctor Who.  Of course, the main similarity is the way the eggs are laid and hatch, and as the Doctor points out, that's very similar to certain terrestrial insects.
