Can someone explain this to me? I'm debating this retard and he posted this picture I'm not sure how to disprove it. I know the constellations move around but some of them like the Big Dipper are visible throughout the year. I feel like I'm missing something, but I'm not very knowledgeable in this field. Any help is appreciated thank you.

YES, the constellations move throughout the year, but every 6 months NONE of the stars from the 6 months prior should be visible. Also How did they calculate the distances between astronomic bodies? Estimations on top of Estimations

Images, not photographs. Don't believe this CGI he's posting. If NASA or the Chinese agency sent pictures of a unicorns ass would you believe it? Appealing to authority is an argumentative fallacy, and they expect you to cave to it.

Are we circling 360 degrees around the sun? Every 180 days we should be on opposite ends of the orbit, with COMPLETELY different constellations. We only see a shift with a few new constellations throughout the year. You shouldn't be able to see ANY of the stars from other seasons, because we are facing out the total opposite way. This is the question no one can answer but will strawman to hell.
