Does truth exist?

Thousands of years back, the world believed that earth is flat and that was the truth until Erastosthenes (350 BC) discovered it was round and then Aristotle proved it was a sphere. Another opinion thats a truth was the concept of the centre of the universe. Until 16th century, people believed earth is the centre of the universe until Copernicus discovered its the sun which is the centre. But now with more galaxies uncovered, there is no clarity whether there is any centre.  

Out of all these truths, which is the real truth? Does absolute truth exist?

Evolution is proof enough that man has seen truth changing or evolving as time has moved. What was truth in 500 BC was found false in 350 BC and what was truth till 1600 AD was disproved with a new discovery. So what's truth dependent on? Is truth dependent on knowledge or time or new revelations? Or is it apt to ask ourselves if any truth exists?

Even our beliefs or values or cultures have evolved overtime. What was believed as sacred became mundane overtime. In fact the word culture itself means "tending to earth or grow or nurture". Culture ceases to be culture the moment it becomes rigid. But what is man stuck in? When adults see youngsters with mobiles and games and living freely, they tend to say, 'This is not our culture..bla bla bla'. Do they even know what existed in their ancestors time? What are we holding on to as ours?

Culture stays culture only when it evolves and grows and moves ahead. And that's what our young generation are showing. They are innovating and inventing new ways of being and doing, which we as adults can't comprehend and accept. This is only because we are fixated as to how our culture is and should be.

If cosmological truths (which the whole world population believes) themselves can be found false, how sacred are our nations truths, states truth, families truth or our own personal truths?  

How about exploring in your own world what myths you hold as truths and are missing on the real life happening outside?
