Marathon was not a war, it was one battle in a 50-year war between Persia and the Greek city-states. The most important battles were Salamis, Plataea and Mycale. The significance of Marathon is that it was the first time that the Persians were defeated, and this Athenian victory showed to the other Greek city states, after nine years of Persian victories, that the Persians could be beaten.
They were rallying calls for the Greeks. The Athenian success at Marathon demonstrated to the other Greek cities that the Persians could be beaten. Thermopylae became another symbol for Greek steadfastness which was used by the Greeks for propaganda on the superiority of the Greek warrior.
After the western Greek citiy-states led by Sparta had defeated the Persian navy at Salamis, the Persians could not feed their army during the oncoming winter and had to send half of it home. The remaining half, with 40,000 Greek allies, was therefore now about the same size as the southern Greek alliance of city-states. The difference was that the Persians had strong cavalry but unarmoured infantry. The Persian infantry could not stand up to the Greek armoured infantry and relied on their cavalry to harass the Greeks. So the Greeks selected Plataea as the right place where they could fight over broken ground where the Persian cavalry could not get at them. The result was the defeat of the Persian army.
No. The Greek forces were infantry. The Persians had cavalry, but it could not operate in the pass or mountains.
Persian infantry was unarmoured - they could not stand up to Macedonian and Greek armoured formations. The Persians first tried hiring Greek armoured infantry, but after winning the battle of Granicus, Alexander had the captured Greek mercenaries massacred as a warning for Greeks thinking of hiring themselves out to Persia. At the final battle of Gaugamela, the Persians had trained their own heavy infantry (Kardakes) but they were too raw and inexperienced to stand up to the seasoned phalanx of Alexander's army.
They were no longer threatened by Persia and could get back to their usual occupation of fighting each other.
The Greek set a trap so that they could surround the Persians.

The Persian infantry was unarmoured and could not stand up to Greek and Macedonian infantry formations, particularly after both raised cavalry forces to match those of the Persians.
Neither the Greek cities nor the Persians could assemble sufficient power and logistic support for a conclusive victory. The wars began in 499 BCE with the Ionian Revolt against Persian rule , and continued until 449 BCE when the Persians gave up trying to pacify the Greek city-states and left them to go back to their usual fighting amongst each other.
Because the Greeks found an extremely narrow canyon, about 20 ft, where they fought knowing that the Persians could not suround them, so numbers would not be such a large factor. The Persians knew this, so before clashing swords the rained upon them with arrows for one day straight, devistating the Greek army, then from the cliffs the tossed down boulders. later they found a passage around and surprised the Greek army from behind, destroying them. There were 3,000 Greek casualties and 2,000 Persian casualties in the end.

The Battle of Marathon had shown to the Greek city-states that they could thwart Persian invasion forces and also proved that Greek armour and tactics were superior to those of the Persians .
One of the best ways for a small, defending Army to defeat a much larger one is to pick the battleground. For example, in Ancient Times, King Leonidas of Sparta defeated a much larger Persian army because they fought at the mountain pass of Thermopylae. The spartan men could line the entire mountain pass, however the Persians could only deploy a few men to attack. There is historical question about whether this battle was a true victory for Greece, as the Persians did eventually get past the Greek forces, however I believe this to be a Greek victory, as many Persians were lost. On the offensive, one should use his men wisely, make no sacrifices, and remember it is okay to retreat. Google Leonidas or Alexander the Great to see historical examples of tactics beating strength in numbers.
The Persians had put down the revolt by the Ionian Greek city-states in Asia Minor. They then moved to punish Eretria and Athens for supporting the revolt. Athens defeated that expeditionary force. This demonstrated to the mainland Greek city-states that Persia could be beaten, and encouraged many of them to resist Persia's attempt to bring them under control.
The Greek were good cruisers, and built good ships that could sail at impressive speeds. They studied the wind and tides, and built strong warships. The Greek naval ship, the Trireme was instrumental in defeating the Persians.
