What Do We Know About Animals?

Aquatic life refers to animals that live in the water and also plants that grow in or on the water. Many scientists have made claims that life began in the sea, and some have said life began on the land. In any view, we know life is evident today in all parts of the earth. Earth is the only planet that supports life to date in the entire known galaxies and planets. Animals have been with us from since the beginning of the earth, and they will remain with us for a long time. The Jewish book of Genesis gives days and times of the creation of heaven and earth. In this creation story, God divided the waters on the earth into two categories; these are: ''seas or oceans'' and ''clouds or skies,'' he also made the dry land and called it earth, when God had done this water was already on the earth. In this story life started in the sea with God creating great whales and fish after their kind, before he created land creatures. Another thing God created after the sea creatures were birds of the air. To believe in life from the sea would be better to understand rather than from the point of evolution from on the land. However, it is still a great mystery in scientific circles of questions frequently being asked of 'how' and 'when' life began. The biblical story of creation is not much different from the scientific aspect of how this earth came about in truth. In fact, scientists used a major part of the Bible to investigate their research. The writer of Genesis clearly noted that life came forth abundantly from the oceans or seas. Life in the sea began in a rapid period of earth's history called ''The Cambrian Period.'' During this time there was a rapid growth of different types of aquatic life in the seas or the world's oceans. This period lasted about 40 million earth years; during this time many species of animals began to emerge in the oceans, some were common others were uncommon. Deep sea corals are some of the oldest sea creatures on the earth, stemming from over 4,000 years of earth's history and also jellyfish from a period of over 650 million years. Some animals from the sea that existed in the predate Earth period still exist today; others are extinct. Sea animals were abundant at the time of the dinosaurs. There were even dinosaurs that lived in the sea, but somehow they got extinct with the rest of dinosaurs on the land. Life in the seas is in a world by itself; there are many mysteries that surround this aquatic world of plants and animals dating from over 500 million years ago when the first animals and plants were developing in the earth oceans. The seas and oceans are one; the oceans ranging from the Atlantic, Antarctic, Arctic, Indian, and the Pacific Oceans are all one large body of water called seas. Water is 72 percent of the earth. Water is what suggests that life exist especially pure water. Water is made up of two elements; hydrogen and oxygen. Only the earth has watery oceans with oxygen as our solar system proves to date.
