An asteroid. This was not what killed the dinosaurs, though. The dinos were destroyed by erupting volcanoes which may or may not have been influenced by the asteroid.
No. The universe itself is about 13.7 billion years old. Earth is between 4.5 and 4.6 billion years old.
Earth did not exist 700 billion years ago, nor did the universe. Earth is about 4.6 billion years old.
No, the earth wasn't around 7 billion years ago. Earth formed about 4.6 billion years ago.
It is unlikely that Earth will be disintegrated in exactly 2 billion years. However, in about 5 billion years, the sun will expand into a red giant, potentially reaching Earth's orbit and causing the planet's destruction.
No, rocks that are 3.5 billion years were not present when earth was first formed. Earth formed about 4.6 billion years ago.
When a Mars-sized object hit the Earth.
No. The universe itself is about 13.7 billion years old. Earth is between 4.5 and 4.6 billion years old.

Earth did not exist 700 billion years ago, nor did the universe. Earth is about 4.6 billion years old.
It is just a fact that earth is 4.6 billion years old.
The Earth is currently 4.5 billion years, so in approximately 2.5 billion years time.
Earth formed approximately 4.5 billion years ago, not 50 billion years ago or 5 billion years ago. This age estimate is based on radiometric dating of meteorites and rocks on Earth.
No, the earth wasn't around 7 billion years ago. Earth formed about 4.6 billion years ago.
Earth accreted about 4.55 billion years ago. The moon followed, likely from the oblique collision of a Mars-sized object with the Earth anywhere from about 30 - 70 million years afterward. This object, along with parts of the Earth, were vaporized with part of it entering orbit around the Earth, slowly condensing into our moon.
The farthest object from Earth that is considered part of our solar system is the dwarf planet Eris, which is about 9 billion miles away. Beyond our solar system, the farthest known object is a galaxy called GN-z11, located about 32 billion light-years away.
It is unlikely that Earth will be disintegrated in exactly 2 billion years. However, in about 5 billion years, the sun will expand into a red giant, potentially reaching Earth's orbit and causing the planet's destruction.
