Alfred Wegner developed the theory of plate tectonics, not a theory of a shrinking Earth. The Earth is not shrinking and no scientific theory has ever proposed that it is.

Wegener proposed the theory of continental drift, suggesting that the continents were once connected in a single landmass called Pangaea. He proposed that the continents drifted apart over time due to the movement of the Earth's crustal plates.
One theory is the Big Bang - after that, matter, including Earth, formed inside a solar nebula which later became our Sun.
This is known as the heliocentric theory, first proposed by Aristarchus two millenia ago.

His idea was that the Earth's continents were once joined together, but gradually moved apart over millions of years. The idea was rejected at first as he was a Meteorologist and not regarded as a proper scientist.
