didn't exist
No. If you look far enough away, you will see OTHER objects in the past. For example, if a galaxy is ten million light-years away, the light of this galaxy took 10 million years to reach us, so we see this galaxy 10 million years ago. Earth's light, from millions of years ago, doesn't come back to us, since (roughly speaking) light travels in a straight line, and moves at the speed of light (300,000 km/sec).
At a distance of 1 million miles from Earth, the Sun would appear much smaller compared to its size in our sky. It would look like a large bright star, but not as large as it appears from Earth.
Mars' distance from earth varies a lot, it all depends on where the two planets are relative to each other in their different orbits around the sun. The closest that Mars gets to Earth is near the time when they are lined up, with the earth between the sun and Mars. At this point, Mars can be as close as 54 million km (about a third of the Earth to sun distance). When Mars is on the `other side` of the solar system, with the sun between us and Mars, thats when Mars is furthest from Earth (around 400 million km). Watch out for those hoax emails! In 2003 they said that Mars will be at its closest approach for so many years and the planet would look as big as the moon - this was a hoax. Even though it did come closer to the earth for a long time, you would not have noticed it being any bigger or brighter.
no a dieses killed all the dinosaurs but we may never know if i am wrong or right No, The reason for their ending may be because of the Flood that happened in the Bible, If you look it up in Genesis you can read more.
It is thought that millions of comets rained down as ice on the early Earth and produced the oceans soon after it's creation 4,7000 million years ago. Look at the surfaces of Mercury and the Moon. They are covered in craters but, having no atmosphere and low surface gravity, the water leaked back out into space.
YES
well you never know. No one knows unless you think you'd be alive for 250 million years.... #justsaying..
At the bottom of the planet it was one large landmass that was breaking apart
Nobody can answer this question. There may be no whales by then who can say 65 million years ago dinosaurs ruled the Earth,

It is now known what North America look like 100 million years from now.
Since the Andromeda Galaxy is about 2.4 million light years away, when we observe it, we are seeing it as it was 2.4 million years ago. This is because the light we see from the galaxy today has taken approximately 2.4 million years to travel from the galaxy to Earth.
earth will blablabla
60 million years ago Canada was a mass of ice.
100 million years ago the continents were starting to take on their modern shapes. In this time dinosaurs were the dominant land animals and forests were widespread, with some even existing in Antarctica. There were no ice caps at the poles.
Plate tectonics will probably cause Africa to collide with Europe and Australia will collide with south eastern Asia
The Great Galaxy in Andromeda (also known as the Andromeda Galaxy or M31) is about 2.5 million light years from Earth. When we look at this galaxy today, we see light that has been traveling through space for 2.5 million years; i.e. when we look at the Andromeda Galaxy, we are seeing it as it was about 2.5 million years ago! Think about this, we are looking back in time.1 light year is the distance that light travels in 1 year. Speed of light is 300,000 kilometers/second, find the distance that light travels from the Andromeda Galaxy to Earth in kilometers and express it in scientific notation.
