Viper, why not do some studying of ontology? You might it interesting. Does a hole, say a hole in the doughnut, have existence? Questions like that.
In the Bhagavad Gita it states that there is no existence of the unreal and no non-existence of the real.
One thing i've always gone by is that for Truth to be Truth, it has to be eternal. By this, it was true 200,000 years ago & will be true 200,000 into the future. For example, people, all people seek love. They seek to receive it and to give it. Even your enemies seek love. Often times when people or children are being very mean, it is just a negative way of seeking to be loved.
An absolute Truth is: The very first person you meet whenever you enter a room will be yourself 
Where ever you go in the world and whoever you speak to, you are always meeting yourself. Know thyself. What did your face look like before you were born?
