Please helppp. Is manned space travel worthwhile or is it better to use robots? Explain your reasoning

I think robots would be better. Even though it might take time or take a lot of money to make the robots, it is safer than sending humans into space. Also, if we were to send a ship somewhere far away in our solar system or even past it, it would be hard for humans, and they may not even survive long enough to get there. Robots, however, can survive longer, and, since they are programmed by humans, we can program them to record the data in space, and they can constantly record space as they travel. We also would be risking less lives, and wouldn't be putting too many risks on the survival of the humans sent into space. The only downside would be that the robots can malfunction, but other than that, robots are better. :)
