What exactly is a LIE?

We most generally conceive a lie as that which is not true and that which arises during communication. But there lies the first fault, we cannot, at least with the present technology, say that only human beings can communicate. Hence the definition of a lie is inadequate in case of animals, insects, microorganisms, etc.. I would also like to touch one point, how important it is to be phychologically superior to tell a lie. As an example, a grown up is much more developed than a toddler, but to my experience, I can say that a kid may outsmart its parents in lying. In a similar fashion, can an insect lie? Well we can't be sure, or can we? Thus there must be another definition of a lie, which I think none of us knows. A dictionary will say- A lie is a false statement deliberately presented as being true; a falsehood or something meant to deceive or give a wrong impression. Well this suffices for us 'literologists' but is it good enough for our scientific community. Science demands another explanation. To give starters an idea of how to begin thinking on this complex topic, I prefer an example. Consider me telling my boss that I would be unable to come to work the next day due to illness, but I go to the movies the following day. This certainly is a lie. But if it so happened that I woke up in the morning and found myself ill, would the lie I told my boss be actually a lie? Here the point is timing. The lie had existance till I woke up in the morning, after that it became the truth. So can I (I am a bit doubtfull about my opinions as my esteemed readers will be generous enough to correct me if I am wrong) say that an event till it occurs is a lie and at the instant it actually happens, it becomes a fact, a truth. There are many other examples which I can share but first I need to know if I am on the right track.
