60% of all the stars in the universe is still an insane number. There are roughly 100 billion stars in a galaxy. Now look at this picture, that was shot in no particular direction by the hubble space telescope...was just some empty looking area, and we wanted to see what was in deep space.

life is definitly rare...but rare in something liek that is still a very large number
and clips, the big bang isnt an explosion. It was the start of the expansion of the universe. And technically, explosions did make us. A star exploded, releasing all of the elements it\'s made of (which happens to be mostly hydrogen, which happens to be our most abundant element). A new star form\'s in its place and planets are made of all the excess rock/metals/gas that don\'t get sucked in by the star, those rocks/gasses/metals form the planets. So we\'re made of star stuff.
Can look up how star formations/solar systems form to get some better wording and evidence than from a college student that took a few classes, but this stuff is more for sure than evolution, which we definitly don\'t have nailed down but I think we have the right idea.
