Life on land probably began about 430 million years ago,though it has existed in the water for perhaps as long as 3000 million years.When we think of the first life on land,we probably think of some strange animals coming out of the oceans,but in fact,no animals could have been living if plants had not been on land first.Plants had to be on land before animals arrived.They supplied the first land animals with food necessary to live,since they—the plants are the only form of life that is able to get and store energy.
