Silk is produced by silkworms. They are very small and their silk is consequently produced in very small quantities. It takes much time and effort to process it for commercial use. Sheep are plentiful, and large, and their wool can be processed on an industrial scale, making it very much easier and cheaper to prepare for use in textile manufacture.
Wool comes from a sheep, and silk comes from a silkworm, which it's cocoon is made out of. Wool is a bit scratchier and cheaper, while silk is more expensive, but more luxurious.

Expensive is relative. Some animal fleece -- baby yak, is more rare than other animal fleece -- lamb. Relatively, you'd pay more for yarn spun from baby yak fleece than you would pay for lamb wool.
Silk is well known for being warmer than wool. Nylon and cotton are poorer insulators. (As well, there are other types of "wool" which are known for being much warmer than sheep's wool...)
Wool is much warmer than cotton and silk and jumpers were made to keep us warm. That is why, OK?
