Bulgarian Scientists Converse with Aliens

I could not resist musing on this story I found in the Telegraph news since I am always posing the question about how humans would react if aliens made first contact with us on Earth and now we have this story about Bulgarian scientists claiming that extraterrestrials have been answering questions posed to them, and the answers are in the form of crop formations. Well, my first reaction was to laugh because of the inclusion of the crop formations. I was expecting some form of electronic communication, or an actual confidential conversation with an alien revealed by an anonymous source, but the scientists claim to have asked 30 questions to the aliens and the answers were being given through 150 crop formations. Don't get me wrong, I love to think that aliens are living among us, I have a Star Trek concept about it in terms of we all do not look that much differently from each other and they wish not to interfere in our development, I could believe that governments would cover up alien contact such as in the Stargate series, and I do believe that alien life does exist in the universe, that is why Contact by Carl Sagan is one of my favorite stories.
So my reaction to this story, then is skeptical, but I like that the scientists are insisting that alien life exists, I would like to know more about the 30 questions that have been asked, how they were asked, and how they have been interpreting the answers given by the aliens and how the aliens call themselves. I hope one day we can make first contact and not try to blow the aliens away, conquer, enslave, or quarantine them, but we shall see, we have enough trouble treating each other with respect right here on planet Earth.
