They would find what theory this evidence supports instead (according to AQA exam mark sheet)
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.
Because the theory fits all the evidence so far. There are still difficulties with it and more questions need to be answered but it seems to be the best theory at present.
quantum theory
There was no concrete evidence that led Dalton to propose his atomic theory. He proposed this theory based on logical explanations about the behavior of elements, gases or materials.
It will be replaced by a new theory when enough evidence is collected
For their own benefits.
modify the theory or discard it altogether.

Scientists had made observations that did not fit exactly with Dalton's theory. Scientists changed the atomic theory to include this new knowledge. While the modern atomic theory is based on Dalton's theory, it is also very different.
In the 1960's scientists uncovered new evidence that seemed to support Wegener's theory.
At the time when this theory was a-brewing, it was difficult to provide conclusive data and evidence.
There was no evidence to prove it
Fossils.
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.
Instead of just stating his own personal opinions John Dalton cited evidence to support his atomic theory. The giving of evidence - which could be proved or disproved by others - was what soon resulted in his theory being accepted by scientists.
Each scientists have there own opinion. Some accept theories and some have to have facts.
Wegener's theory of continental drift is supported by a vast quantity of evidence, which is why scientists have accepted it.
