They generally don't. The Giant Impact Hypothesis is generally accepted amongst scientists.
theory
A German scientist Alfred Wegener first proposed the idea of Continental Drift.
It is generally agreed that the M stands for "membrane" though the words magic, matrix, mother, and some others, have been suggested. The scientist who named this theory actually didn't say what the "M" stands for.
Scientists often repeat scientific investigations to verify that the results for a hypothesis or a group of hypotheses are correct. This can lead to a scientific theory.
The scientists realized that the continents were much older, leading them onto the theory of Sea Floor Spreading!
why did other scientist not accpet Alfred Wegeners theory
Just accept his theory.

theory
A scientist's theory might not be believed even it is correct, if the theory is such a radical departure from existing beliefs that it seems bizarre. The theory of continental drift (which, of course, was eventually accepted) was resisted for decades because it just seemed obvious to people that the continents are not drifting, since we do not notice any such motion. It could also happen that a scientist has a valid theory but has not adequately explained, or experimentally tested that theory. Other scientists require evidence in order to accept a theory.

Because if scientists aren't open-minded, they could try to discredit or change the results of a valid experiment, or not accept a theory that may actually be right, and discredit the theory, therefore stopping progress in science.
