If a planet like earth disintegrated, would life survive as dust drifting through space?

In nearly every part of this planet, there is some kind of life. From the deepest oceans to the highest mountains, some kind of life exists there. Imagine if long ago there was a planet just like Earth with life tered all over it, but one day, a giant asteroid collided with the planet and it disintegrated tering a cloud of life bearing dust into space. Somehow, life survived on this dust as microscopic organisms and one day, millions of years later, some of this life bearing dust landed on Earth. Some of this dust also landed on Mars, Venus and all the other planets and moons in our solar system but only earth had the right conditions to allow this life dust to survive and evolve. Eventually this life dust evolved into all the kinds of life we see on Earth today. Isn’t this a much more plausible explanation for life on Earth than some stupid bible myth about an invisible god?
