Does a Jehovah's Witness believe in evolution or creationism?

Jehovah's Witnesses believe in creation as outlined in the bible.

They do not believe in evolution and believe the earth and its lifeforms were created in six ''creative'' days of 7000 solar years each. (Not six 24 hour days). They believe that the universe and the earth itself would have been created millions or even billions of of years ago. But the actual creating of the earth as a habitable planet would have started 48,000 years ago.

Also 4380 years ago they believe that all life would have had to spread around the earth again after Noah's Flood in the year 2370BC.
