If Earth is still the same planet of the dinosaurs, then if we fastforward time, dinosaurs will be back?
Dinosaurs still rule the Earth, though.
>not even if the universe was cyclic.
I that case why not? We like to assume that life would be totally different than ours on other planets. But they have the same physical and chemical laws. Life if still probably going to be based on carbon since its a freely availabe element and it likes to hang around with other atoms. Is it that hard to assume that the same thing that happened here can happen elsewhere, or maybe in a new cycle of the universe? What can happen will probably happen again and again

They probably gave up frogs...

Sure thing, kiddo.
You're right, though, neither dinosaurs nor synapsids have ever ruled the Earth; insects did and do.
Since when is the ability to build a skyscraper a primary indicator of species success (particularly if a lot of the processes that allowed us to build skyscrapers might happen to challenge prospects for decent species survival)?
The most successful organisms (things like bacteria, beetles, plankton, etc.) tend to be relatively simple.
