I do not think the invisibility cloak would help the world

so that we no that when a asteroid are is going to hit

Very thoughtful. Great comment!

If any body has read War of the Worlds or has simply done a science experiment (I know those are two very different things, but trust me, they connect) then you would know that if you even change the tiniest thing in any of the variables, you'll know that the result will conclude differently. I think that if any microbes from Earth came i contact with alien life that it would definitely change the outcome had it not. So, I think maybe observing before we jump to see what is going on is most likely a better option.

I think that it would be fun to be at the Nobel prize or win it.

I thing that we would become a alien or the alien would become one of us.

Well, for one, if the ice hotels were permanent it would go from "The Ice Hotel" to "The Puddle". I'm sure the sand would last a little while but erosion would take a great deal of it away. Also, if you keep a special thing like these hotels in a certain place and you are able to preserve them, they wouldn't be as special anymore. You just lose interest and when you walk down the street with your friends you just start saying, "Oh, yeah. Look, somebody's tongue got stuck again on the ice on the door. I guess they'll just have to call the Ice Police." See, you just start getting used to it and that's probably not one of the people who build these things goals.

I think that the selfie I will remember is when I did a 5 mile hike in yellow stone to the fire tower.

That for his age he was going to run for his birthday that would make me do it when I am 105 for my birthday.
