My short answer is: YES.
This same answer but longer is: Look at the amazing indie games that's here in Itch.io. Now, look at you - you are the exact same species, or race, as who built whatever indie game is it. So where is the logic when i say that you is not capable to do whatever another person already did (in the past)? You just have to know well, where you want to reach - how is the game you want to make.
