What makes the earth unique when compared to other planets?
I can't say there is much that makes Earth special or unique. Earth may harbor life now, but other planets have done so before as well. There is a universe full of planets and potential life. There may possibly be 1 million other Earths out there, much like our own. But if you just want to compare the Earth to the solar system, you could say that it currently has intelligent life, even though there may be life on mars.

How is Uranus different from earth?
Earth is different from Uranus because earth supports life and has an acceptable temperature. It also holds a large quantity of water..Even Though Some Other Planets Show That Water Was Once There..

The Main Difference Is That Earth Supports Life And Uranus Doesn't!!!!!And it smells like farts in Uranus.

What was the earth's atmosphere like before photosynthesis?
Without life because when plants do photosynthesis, they produce oxygen.
Was oxygen on Earth before or after life on Earth?
Elemental oxygen did not appear on Earth until some time after life did. In fact, the oxygen was produced by life carrying out photosynthesis. The first organisms on Earth were anaerobic, meaning their life processes did not involve oxygen. To most organisms like this, oxygen was highly toxic.

When did life on earth begin to evolve?
Scientific evidence suggests that life began on Earth approximately 3.5 billion years ago. The Earth formed 4.5 billion Years ago. The Earth was a dead planet for about 1 billion years. Some evidence would suggest that the first forms of life began more like 3.8 billion years ago, in which case the Earth was dead only 700 million years. The study of the processes which resulted in the beginning of life is called Abiogenesis. If it worked the same on other planets on other Sun in other galaxies, life may have begin 10 billion years ago in other galaxies. See related links. Note also that there are dozens of explanations for the beginning on life on Earth, including many based on religion.
