Aliens, prepositions and more!

Read through this short piece. Can you guess what the missing words are?

I've always been interested _1_ aliens, I never get tired _2_ reading and watching shows about them.

It all started when I was very young, my parents took me to see the movie E.T. It's the story of a cute alien who is left behind _3_ his fellow aliens by mistake. I was blown away by the movie and from that point on became obsessed _4_ the thought of life on other planets.

I definetly believe there are aliens out there, how else can you explain all the reported sightings and stories _5_ abductions?

And I'm not the only one, I read somewhere that 1 in 5 Americans believe _6_ alien abductions, and 1 in 7 Americans say that they, or someone they know, has had an "encounter" _7_ a UFO.

There are billions _8_ other galaxies outside our Milky Way galaxy - plenty of places where life could emerge and evolve.

My dream _9_ life is to see a U.F.O. or even meet an alien in person! I wonder _10_ we would say to each other?
