No, but it might possibly be theorized that the materials required to spark life on planet Earth could have been delivered in this way. Comets and meteors are also possibilities of the same effect.
The earth was attacked by asteroids, formed water, freezed (Snowball Earth) , melted, formed land, grew plants, evolved animals, created dinosaurs, attacked again by asteroids, freezed (Ice Age) , evolved humans and phew! After 4.5-4.6 billion years, humans arrived!

Presently unobtainable ones, such as asteroids. If they are obtainable they are used otherwise they are not resources.

Living on an asteroid would be extremely challenging due to lack of atmosphere, gravity, and resources like water and oxygen. The conditions would be harsh and inhospitable for humans. Additionally, the low gravity could have negative effects on the human body over long periods of time.
the asteroids crashed in Asia have 1000 asteroids
