Life on land held many advantages for early amphibians. There was a large food supply, shelter, and no predators. In addition, there was much more oxygen in the air than in water.

Are there more land or water animals?
The first animals to walk on land are unknown. There is evidence that soft-bodied arthropods and slug-like animals visited the land as far back as 510 million years ago, in the Cambrian era, leaving behind mysterious tracks called Climactichnites and Diplichnites. These tracks are mysterious because no fossils have been found of the animals that made them. Some of these trace fossils are as wide as four inches. Perhaps these animals did not actually breathe air, and only slimed along on land for short periods as a way of moving from pond to pond.
