All grand theories are hard to believe at first because they do not necessarily fit into conventional thought of the time. It takes time for new experiments to be thought up of based on the hypothesis and for them to be run. Often times the technology to support these experiments have not been invented yet.
This was harder to prove because it was not easily visible.
Fossils found on separate continents that are now far apart provide evidence for continental drift. Similar fossil species found on continents that were once connected suggest that these landmasses were once united. Additionally, matching rock formations and paleoclimate evidence from fossils support the hypothesis of continental drift.
Alfred Wegener was the scientist who proposed the idea of continental drift in the early 20th century. He suggested that the Earth's continents were once joined together in a single supercontinent called Pangaea, which later broke apart and drifted to their current positions.
The main objection to Wegener's hypothesis of continental drift was the lack of a plausible mechanism to explain how continents could move. Wegener's idea of continents plowing through solid oceanic crust was not supported by scientific knowledge at that time, leading many scientists to reject his hypothesis.
Alfred Wegener, a German meteorologist and geophysicist, proposed the theory of continental drift in 1912. He suggested that thermal convection currents in the mantle cause the movement of continents over time.

continental drift
Scientist rejected Wegners hypothesis of continental drift at first because he did not have enogh evidence to support his theory. He failed to provide a suitable mechanism that could cause the continents to move.
The hypothesis you are looking for is continental drift.

I think that continetal drift replaced his theory
People thought he was crazy and not very smart but he proved them. He found a way.
