Scientists say when asteroids showered on Earth they were the ones who brought water to Earth which started life. But how did few molecules of water started life on earth?

Asteroids impact Earth on a daily basis, but the vast majority of them are small and burn up in the atmosphere before reaching the ground. Significant impacts, such as the one believed to have killed the dinosaurs, occur much less frequently, with an estimated rate of one every 100,000 years.
Yes, asteroid impacts have been linked to several major extinction events in Earth's history, including the one that wiped out the dinosaurs 66 million years ago. However, mass extinctions caused by asteroid impacts are rare and usually occur only when the asteroid is large enough (over 1 km in diameter) to cause widespread devastation.
Scientists use telescopes and other instruments to track the movements of known asteroids and identify potential impact risks. They also use computer models to simulate the trajectories of asteroids and determine the likelihood of impact. The most dangerous asteroids are constantly monitored by organizations such as NASA's Near-Earth Object Program.
A large asteroid impact could have catastrophic consequences, including widespread destruction, tsunamis, and global climate change. Depending on the size and location of the impact, it could also lead to long-term effects such as a nuclear winter, which could have a significant impact on life on Earth.
There are several strategies that scientists are currently exploring to protect Earth from potential asteroid impacts. These include deflecting the asteroid's path using a spacecraft or changing its composition through a technique called "gravity tractor." Early detection and tracking of potentially hazardous asteroids also play a crucial role in developing effective mitigation strategies.
