This is all well and good, but I could have told them how the solar system got here......for free.
I don't want to sound like a party pooper, but if a celestial object is coming to wipe us out, that means God is punching our ticket.
I'm enjoying what NASA is doing, but let's build staions on Mars or something.
There's my humble $0.02
God tests us all every day. Some tests we pass, others we fail.
If God wants to punch our ticket, with no test whatsoever, then you won't even see it coming.
Otherwise, if you can see it, then it is a test. Some will choose paths that fail; others will choose more wisely.
