In science and physics, if new, legitimate evidence surfaces that doesn't agree with our current theories, then either the theory must be severely modified or it must be scrapped entirely.
A good example would be with Isaac newton and Albert Einstein. Newton discovered gravity and invented the math that we still use today for everyday tasks. But Newton was actually wrong. Einstein showed us the new picture of gravity, which isn't a force at all but rather a shape of space and time, and we just move along the curves of the fabric of what Einstein called spacetime.
The only reason we didn't scrap Newton's equations though is because the difference between the two theories only becomes really noticeable when you're moving close to the speed of light or around a massive object like a sun, galaxy or black hole. So for every day experience the change is so small we can't notice the difference except with extremely sensitive equipment.

Each scientists have there own opinion. Some accept theories and some have to have facts.
Because technology might change in the future.
scientific theory
Wegner's theory was not accept because he didn't have much evidence to support his theory with and scientists thought that there might have been a land bridge between the continents. Another reason to why his theory was rejected was that he was a foreigner, by that; the scientists didn't really take him seriously.
modify the theory or discard it altogether.
If new evidence does not support a scientific theory, scientists will most likely
They do the experiment again, double check all their calculations, then they come up with a new theory if it's necessary. That's why there's no such thing as a scientific fact, only scientific theories.
Like all accepted scientific theories, there is a general consensus amongst scientists across the world that there is enough evidence from observation and experimentation to support it.
No. There is no scientific evidence to support this theory.
a sysrem or collection of such ruls
In the 1960's scientists uncovered new evidence that seemed to support Wegener's theory.
Fossils.
Scientists did not prove things then anymore than they prove things now. Evidence, masses of converging evidence support the theory of evolution by natural selection. Darwin, in his day, had much evidence to support his theory. All the way from artificial selection to island biogeography. Since that time the theory has moved on to where it is no longer just Darwin's theory, but modified and supported with so much evidence that the theory became the bedrock of biology.

Discard it all.
Because non-scientists do not understand what a scientific theory actually means. It is not a random guess. Scientific theories are formed based on evidence and experimentation.The scientific community advocates evolution because all the evidence of life on our planet supports the theory.
