With time you will understand the new navigation and then you won't want to go back to the old navigation. It takes about 1-2 weeks for some to get used to the new navigation. But... if you refuse to us it, then you can go to settings -> display -> system navigation and switch back to the old way of moving around in android
I looks like you want to enter the app drawer. Don't swipe from the bottom. This will activate the home button gesture. Swipe up from the middle of the screen
