All my friends disagree with me on this but I’m sure I’m right:

If you go back in time a million or so years and move a single grain of sand in the middle of the Sahara desert a millimeter to the left, leaving this the only thing changed, have you impacted the future (present) in a meaningful way (e.g. a measurable change, human history, state of the earth, etc.)

90% of my friends say “no” and claim I’m taking “the butterfly effect” way too far and nothing would change. Even some people who agree with me are more reserved such as “it may or may not change the future” when I know for a fact it would. Want to hear some other perspectives. Make me believe you if you disagree, if you agree help me better formulate my opinion.
