The Moon's Tear symbolizes Isis's tears, and the later flood. You get the tear after you do the cave of the nymphs sequence, and look through the telescope(become a being of light). Majora's Mask ends with a rainbow. God used the rainbow to mark his promise that he would never flood the world again. Here they allude to the flood with Isis's tear, show you the rainbow at the end, and the next game released was Wind Waker. The Wind Waker was entirely flooded.
It's a satanic inversion of the story. They are making god into a liar who floods the humans after the rainbow.

https://zelda.gamepedia.com/Moon%27s_Tear Moon's Tears are fall from the surface of the Moon to Termina, so named by Professor Shikashi because they fall from what appears to be the Moon's eye.[1] They're rumored to be the shiniest stones in the world and are consequently highly valuable.[2]
Professor Shikashi keeps one of these rare stones in a display case, which the Skull Kid threatened to steal.[3] Link can acquire a single Moon's Tear for himself by peering through the telescope in the Astral Observatory. When Link takes a closer look at the Skull Kid,[4] who is fooling around on the top of the Clock Tower,[5] a Tear will fall from the Moon and impact just outside the observatory with a bang. Afterwards, the Skull Kid will taunt Link and disappear. The young hero can then find it embedded in a small crater where it landed, just within the fenced area outside the Observatory door.
