After watching all the theories on what could happen in the next infinity war but i couldn't help but realise that Thanos lied about killing half of the universe.
If you think about it there were people in cars,planes,boats ect. That were full of people im guessing that these things missing drivers almost definetly caused more death than half there is also the fact that people in ambulances died in a crash or didnt get the help they needed because the doctors evaporated aswell as the surgeons operating on people disappearing even on other planets i am sure these terms would apply.
That is why i think he lied do you agree or disagree give your reasons in the comments
