It would be impossible for oxygen requiring organisms to exist before photosynthetic organisms because there was not oxygen in the atmosphere for these organisms to breathe. Photosynthetic organisms take carbon dioxide and water in and create oxygen as waste. Before these photosynthetic organisms existed there was not enough or any oxygen in the atmosphere for organisms requiring oxygen to survive.
Yes
The Earth - with some stuff around (or above) it.
Creatures that die before they can breed have ancestors but do not have descendants.

It is classified as extinct when there are NO animals of that species left, not one.
You need to say what the discovery is that you have in mind, before anyone can answer.
The discovery of the wheel happened before the discovery of writing. There is no record of who discovered the wheel.
No organisms could survive before ozone. It is because UV rays would destroy all.
These features were used to classify organisms before the development of DNA analysis. This way, scientists were able to look at certain morphological traits to classify the organism and then correlate them to their closest relatives. For example. Although bats are a lot like birds, certain morphological traits allow them to be classified as something other than birds. i.e. they are mammals - they have similar bone structure to most mammals In this regard, it is based traits other than their wings that they are classified as mammals, and not birds. Hope this helps
The Discovery launched before 1602 was captained by Christopher Newport and whose voyage resulted in the founding of Jamestown in 1607
The scientists basically research carry and number of experiments which are later vetted before a discovery is announced.
Before Edward Hargraves made his discovery, many were traveling to California to find gold. He inspired the Australian gold rush in 1851.
