Will We Ever Be Able to Resurrect Species That Have Goed Extinct?

Will we ever be able to resurrect species that have gone extinct? If so, should we do so? Is this a way for us to undo damage that we've in nflicted on an ecosystem? Or would't we just be playing god and pok everything up again? It's very likely that we can bring back a mammoths. Dinosaurs are a little harder, but mammoths and thylisenes, the so called tasmanian wolf, or t asmanian tiger, also, could easily come back. Although there are people who say that thylocenes still exist. That is one cryptid that i think actually could have a good chance of being real
