Nope. I believe other minds exist. I believe an external reality subject to the laws of physics and chemistry exists. I believe the many parts of planet Earth I've never visited exist despite my ignorance.
I believe other planets orbit our sun, and still other planets orbit other suns. I believe our galaxy has about 10^11 stars, most of which are orbited by multiple planets. I believe the universe contains about 10^12 galaxies. And I would be shocked if intelligent life hadn't evolved independently on many planets in each galaxy.
