Unrefrigerated raw beef almost 6 hours

I left raw marinated beef unrefrigerated from about 4:20-9:50, so about 5.5 hours... It was about room temperature when I touched it It was also only about one serving in a tight ziplock bag I asked a friend who's really into cooking and she said to cook it fully and it should be fine and that I could just store it in the fridge for later, but I want to be sure before I actually eat it. Is it safe?

Websites say 1-2 hours, 4 hours, or chef's rule is 6 hours. Please let me know!
