Well, if they attempt a landing in my neck of the woods, I'll show them some love. I'll be on the cover of every newspaper with my alien body offering to sell it to the highest bidder.
And if I can figure out how to fly their landing craft, my buddy and I will take over that 2,000 mile long ship. We'll have a 3 day long party for everyone on CC, then we're going to sell it to the highest bidder (excluding Russia, N Korea, Iran, France, Germany... oh hell, the list of who we would sell it to would be shorter: America).
