What does Earth have that other planets don't, the basis of life? Water, of course.
Humans and other mammals drink specifically <em>freshwater</em> though, which is far more precious and less abundant than saltwater.
Fossils.
Early in the 20th century, Alfred Wegener, primarily, established the continental drift theory. According to Wegener, continents are mobile on the surface of the Earth and were previously connected to form a single supercontinent. Scientists did not think that the continents could migrate when Wegener was alive.
In rocks that are the same age but on continents that are currently far apart, ancient fossils of the same species of extinct plants and animals can be found. Wegener claimed that the species had coexisted, but that once they died and become petrified, the lands had separated. According to his theory, the creatures couldn't have crossed the seas.
1. Glossopteris seed fern fossils were too heavy for the wind to carry them that far.
2. Mesosaurus was a reptile that could swim, although it could only do it in freshwater.

Answer: Persia is a historic region of southwestern Asia associated with the area that is now modern Iran.
Two artifacts found in the same stratigraphic layer are assumed to be of similar age due to the Law of Association.
The principal laws of the association are contiguity, repetition, attention, pleasure-pain, and similarity. The fundamental legal guidelines were formulated with the aid of Aristotle in about 300 B.C. and by way of John Locke in the 17th century.
Aristotle counted 4 laws of association when he examined the techniques of remembrance and recall: The law of contiguity things or events that occur near each other in space or time tend to get related collectively in the thoughts. Laws of the association are the principle underlying the connections inside the memory between certain ideas, feelings, or behaviors.
Aristotle's analysis of gaining knowledge of memory consists of four laws of association: the legal guidelines of continuity, assessment, frequency, and similarity. Accounting for learning and reminiscence in phrases of such legal guidelines of affiliation is referred to as institutions.
