Firstly, allow me to explain something here. I recently decided to create a blog in order to send messages to extraterrestrials in a language that they will probably understand better than English: Binary code. This was a poor choice and I have since deleted the blog. However, I have attached (copied and pasted) the original so-called extraterrestrial comments to this post in the comments section. This idea originated from certain crop circles that have actually shown up that contained binary code. If extraterrestrials use it in crop circles, then they would have no trouble reading blog posts written in binary code.
Most humans of Earth are aware of extraterrestrials visiting the Earth, but I began to question why extraterrestrials were not responding to human's attempts to communicate with extraterrestrials. After a lot of thinking about this I came to the conclusion that although some extraterrestrials may be able to fluently speak an Earth language, they simply may not know how to write that same Earth language on paper, or via the Internet.
This lack of written languages hinders our communication with all extraterrestrials and vice versa. I personally am aware that some extraterrestrials are capable of, and from time to time, do access the Internet. Therefore extraterrestrials are able to go onto website and peruse what is on each website.
Despite this fact about extraterrestrials, it is not heard of extraterrestrials actually leaving a reply on someone's website. Learning an Earth human language may simply be too much of a challenge for extraterrestrials.
