Why has the spontaneous generation been discarded?
This question regards the earlier theories as to the origins of life. This theory came to be rejected as genetics and the biochemical pathways to life came to be understood through evolutionary biology.
What makes a hypothesis become a theory?
A hypothesis is used to make predictions. Experiments are carried out to test these predictions. If the outcome of the experiment was not as predicted then the hypothesis is falsified. It is either rejected or modified. If the outcome of the experiment confirms the prediction then that provides some evidence that the hypothesis is true.Over time, after testing different predictions, there will be a significant amount of evidence in favour of the hypothesis, and all the main alternatives have been rejected. At that stage the hypothesis becomes a theory.

What is true about scientific theories?

There must a strong suggestion that the claim of the theory is true, but a formal and sound proof has not yet been found.

Did the scientists that rejected Wegener's continental drift theory use the scientific process?
Yes, and using what was known about the earth at that time Wegener's continental drift theory was so implausible that it had to be rejected. It took data secretly collected by the US Navy after WW2 to account for strange magnetic anomalies that interfered with precision navigation of warships and submarines to give the first hints of a plausible mechanism. But since this data was classified for a long time it was not available to the scientific community, long delaying acceptance of the theory. When the theory was finally accepted the name had been changed to plate tectonics, because it wasn't the continents drifting it was the plates shifting (both continental and oceanic).
