I know I'm biting unnecessarily at this dangling worm but:I don't think anybody has the answers on how old the Earth is. It's all speculation imo. I do think that humans co-existed with dinosaurs, however.
Plenty of my fellow geologists have a prety decent idea that the earth is around 4600 million years old, based on known isotope decay rates and ratios, havingatined the oldest known surface rocks at 3000ish million years and relating those (since crustal rocks are naturally remelted and recycled) to the ages of practically every collected meteorite that's landed on the planet being 4600 million years old - which logically will be the left over debris of the formation of the solar system.
Confidence for this data is so strong that a very very few meteorites that have been found to be that are older and having different mineral ratio composition, suggesting that we can detect those that have arrived from outside our system.
There have been no, zero, nada, NO finds of dinosaur bones since 66 million years ago strongly suggesting that that is when they last existed - along with many other species. Humans have been around for a maximum of 3 million years, according to current data finds, but only 1 million years ago, as being recognisable as today's humans. This represents a time gap of 63 - 65 million years between dinosaurs and man. Maybe a bit less if we include @Methuselah
Of course no evidence is proof, and clerics, who's livelihoods and wealth depend on tradition and faith carrying on despite evidence, learning, logic and evidence, will always point to the fact that an imaginary being could have planted this misleading evidence to fool us. They're being very thorough in that case - and also must have nothing better to do.
