摘要：
The question of the origin of water on Earth has been a puzzle since long. The standard scenario that comets have deposited water here over eons has many loopholes, and some recent results have put a question mark on this. Instead, asteroids have become the favorite candidates for ferrying the water. At the same time, other discoveries seem to hint towards a large reservoir of water inside Earth.
