I was hoping he would touch on the Hagerman Fossil Beds National Monument, which has horse fossils. Also interesting that the modern Asian elephant is more closely related to mammoths than to African elephants.
The earth is younger than this to me, granted I’m just a cashier at Costco but millions of years to get to the period of humans “to bring to pass the immortality and the eternal life of man” is just too much time, to me.
You do realize that we're all made out of star dust, correct? I kind of think that we are of such immense value to God that billions of years and massive cosmic explosions and accretions repeated over and over again show that we are 'worth' quite a bit. Don't forget that every single moment we're taught by BOTH Joseph Smith AND modern science that worlds are being created and destroyed constantly. And you are also making the mistake that because we are the work and glory of God that such precludes other things from also being manifestations of His glory. Hugh Nibley pointed out that in the scriptures where it states that there is no place where there is no kingdom and that there is no kingdom where there is no space demonstrate's God's perfect economy. Nothing is wasted. If we mess up or squander our opportunity God has insured that some other life or being can benefit and gain. There's literally no waste. If we through our agency and myopic view don't see it doesn't mean it's not there, that there's not some great wonder happening.
The Native Americans disagree with you. You don't become a people of the horse in just 100 years. American mustangs are on average 2 hands shorter than spanish horses. That didnt happen in 400 years. Dont be so naïve.
