Would the world be ready to accept aliens from another planet, if they did exist?

We all have heard the stories and seen many movies of Extra-Terrestrial life. Little Green Men, The Blues. The Grays and so on.

If in fact there are aliens and they purposely wanted to be seen would you freak out or would you be able to take them in stride?

Would you be able to accept them into your home and offer them a hot cup of oil and some steel bars for lunch if that is what they needed to survive?

If they asked to put their finger in the wall socket would you be okay with that?
