Sort of false - it was about 1.5 billion years ago.

There were no chimps 1 billion years ago. At that time all life was single celled organisms and rudimentary multicellular ones.
For about how many years do astronomers believe the solar system has existed?
Answer 1It has been around since God created it. Its not gazillions of years old. Dont believe that crud. It all a lie. The universe has no real creation date. Please read the bible, it will help open your eyes to so much knowledge. I'm not begging, just a suggestion to the reader.Answer 2The latest astronomical data shows the universe to be around 13.7 billion years old.
What were the continents called when they were all together?
When the continents were all together, they were called supercontinents. The Earth is thought to be 4.6 billion years old. The oldest theorized supercontinent is Vaalbara, which may have formed 3.3 billion to 3.6 billion years ago. The oldest known supercontinent is Ur, which formed 3 billion years ago. The Kenorland supercontinent formed 2.7 billion years ago. Columbia formed 1.8 billion to 1.5 billion years ago. Rodinia formed 1.1 billion to 750 million years ago. Pannotia, which also is called the Vendian supercontinent, formed 600 million to 540 million years ago. Pangaea formed 500 million to 200 million years ago. Laurasia formed 200 million years ago. And the last supercontinent was Gondwana. But that title may be held only temporarily by Gondwana. For the future may hold possibilities of one or two supercontinents within the next millions of years.
When was Neptune formed?
About 4.5 billion years ago, along with all the other planets.
Did the Milky Way Galaxy explode fourteen billion years?
Stars that now exist within our Milky Way -- indeed, all stars themselves -- did not exist till about 13 billion years ago. Our galaxy did not take its present form till about nine billion years ago.
Is it true that the ancestor of all eukaryotic cells evolved about 2 billion years ago?
yes and no
Did the Milky Way explode fourteen billion years ago?
No. The milky way did not exist at all, fourteen billion years ago. According to the Big Bang theory, the first galaxies started forming at least a million years after the universe had started to expand.
How long has Jupiter been a planet?
4.5 billion years, like the rest of the solar system
How did the earth come to be before the radiation of the big bang traveled here?
If you are referring to the cosmic background radiation that pervades all space with an ideal blackbody temperature of 2.7 degrees Kelvin, the earth formed long afterwards. The universe began as a hot, dense, inflationary expansion of "energy" 13.7 billion years ago. Our earth is 4.6 billion years old. The difference is 9.1 billion years.
Is there dinosaurs when the earth was formed?
Not that anyone knows of. Though theories have been proven wrong before, all Dinosaur fossils that have been observed have been from 65 million years ago or older.
