Most scientists believe that an infinite dense singularity existed before the incident known as the Big Bang.
I believe most scientists would agree that this is not currently known. Some, however, would say that there was no "before" - that time itself started with the Big Bang.
As of yet, there is no majority opinion on that yet. There are various hypothetical models on the origination of the universe, foremost among them several variants on M-theory, but no way to establish a preference for any of these models.
they were....long!
None in our solar system. Scientists believe that Venus might have has one like ours millions of years ago, before a 'runaway' greenhouse effect occurred.
The vetting by the body in charge is the final step that the scientists have to follow before a new planet is announced.

Scientists know that fish existed before amphibians because fish were found in a lower layer of rock.
NATO existed well before the Tonkin Gulf incident.
It was not. Gondwana was a super continent comprised of Africa, Australia, Antarctica, India, Madagascar, South America, and Sri Lanka. Scientists now believe that more supercontinents existed even before Pangaea. One of them is called Rodinia. Before Rodinia, there was one called Nuna.
No, Pangaea was not the only supercontinent that ever existed. Other supercontinents include Rodinia and Gondwana, which formed and broke apart over the Earth's history due to the movement of tectonic plates.

If you believe in creation, you understand that nothing existed, not even the Nile River, before Creation.
