The physical universe is theorized to have begun in a big bang about 13 to 15 billion years ago.
Our solar system was formed out of a ball of spinning gas approximately 5 billion years ago. When the sun became luminous enough the remaining dust and gas were blown away into space, leaving the planets orbiting our sun.
Earth is in the Orion arm of the Milky Way.
The Milky Way is a spiral galaxy.
The center of our galactic core is theorized to be a black hole.
Our Milky Way galaxy is 100,000 light years wide and 4000 LY thick.
1 light year equals 5.9 trillion miles.
Nearest galaxy (Andromeda) is 2 million LY from the Milky Way.
