Here is a picture of Biden from January 2017. This picture has the dangling earlobe so we know this is the original Biden. Look at his right hand. Notice how wrinkled his hand is. https://myrightamerica.com/joe-biden-puts-democrats-on-blast/
Here is another photo of Joe being creepy. Look at his left hand. https://markinreport.com/wp-content/uploads/2019/04/jb.jpg
Here are a couple more pics, zoom in. https://a.abcnews.com/images/Politics/ap_joe_biden_climate_jc_150616_16x9_608.jpg http://ninelinenews.com/wp-content/uploads/2020/02/joe-biden-dumb.jpg
Now, here is the video of Joe from last nights speech. Joe likes to talk with his hands. There are lots of good examples in this video, we are not dealing with the same Joe Biden from 4 years ago. His hands look way to young. https://www.youtube.com/watch?v=sZBquj94CGU
Be a forensic analyst, Go to duck duck and type in Biden, click on images, perhaps you can find better examples of certain features to prove we are dealing with a fake Biden and post them here.
Bless you!
