Billions of years is pretty hard to prove especially when we have found dinosaur bones with living red blood cells.
Who told you this? This is simply a lie. I don't particularly care either way whether you personally believe in evolution or not, it doesn't affect me.
However, for both our sakes you shouldn't be spreading this particular fantasy - for mine because it causes confusion about evolution, and for yours because it makes you look foolish.
We have
no dinosaur bones at all, not a single one. What we do have is a large collection of rocks which continue to hold the shape and structure of a dinosaur bone that once existed. None of these rocks hold blood cells, living or dead. On very rare occasion small protein fragments may survive, but these in no way constitute any form of living tissue.
I strongly suggest you visit a museum joeboonda, just so you can verify for yourself that fossilised bone is rock, not calcified tissue.
In other words, "billions and billions of years ago a living cell was formed in the primordial soup and now here we are and your uncle was a monkey.
Nearly, replace the word uncle with great-grandfather x10 to the power of 9 and you'd be nearer the mark.
I don't understand why certain people find the existence of their ancient ancestors so offensive. The fact that everyone alive on Earth today can trace their lineage back 3.5 billion years, and can claim the most amazing life forms of this planet as distant relatives should be a source of great pride. It certainly is to me.
I'd much rather recognise that my distant ancestors were simian, rather than pretend they were a handful of clay.
