He lied by including false evidence

Detailed explanation-1: -The main reason that Wegener’s hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth’s spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.
Detailed explanation-2: -The main issue with Wegener’s Continental Drift Theory was he did not have a mechanism behind the drifting of continents. He had a substantial amount of evidence that made sense; nonetheless, without a driving force behind it, the scientific community simply discredited his entire idea.
Detailed explanation-3: -The drift according to him, might have occurred due to centrifugal forces of earth or astronomical changes. Continents could not possibly the way he described it because he did not provide any hard evidence that would give the ultimate cause or mechanism for the continents to move.
Detailed explanation-4: -Why was Wegener’s hypothesis rejected? Because Wegener could not identify the cause of continental drift, most geologists rejected his idea. Continental drift was what Wegener invented. Wegener’s hypothesis was rejected from geologists because he couldn’t identify the cause of continental drift.
Detailed explanation-5: -Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other.
