There is no such thing as an absolute truth, or is there?. Our experience of the world is always going to be limited by the amount of senses we have, how sharp those senses are and the capacity of our brains to make sense of the stimuli around us. Therefore we are basing our understanding of 'truth' on factors that are finite and restrictive.
For example. I am looking at a table. The table is there, it exists. That is the truth. But is it? It is only a table because a human being, a mortal with a flawed understanding of the universe, named it a table. What it really is is a formation of atoms built to resemble a shape. Except every noun and verb I just used in that last sentence is also just a name that we have given to make sense of something when our understanding is hopelessly limited.
Imagine if there were an alien here, with 10 senses, all of which sharper than mine, and with a much larger brain to process all the stimuli. What is the table to him? Can he see things that I can't? Maybe it emits a sound that I can't here but he can? Maybe it is radiating something else entirely that none of my senses can register, but he has a sense specifically for it? Maybe his mind can understand the very basis of the table in far more depth than I can? What would he end up calling the table? How would he define it? He will experience the world around him in a very different way to me, and therefore his 'truth' will be different. But even then it is still based upon limiting factors, just slightly better ones, so his truth cannot be absolute either.
If our understanding and experience of our environments will always be limited, then how can we ever be sure that the statements we make are 100% 'true'? As a result I can't even say 'there is no such thing as an absolute truth' as a blanket statement, because it undermines the very point. I have no idea what 'the truth' is and I never will.
