Until they can see things in real time its all bull chit and ancient history
So you're basically anti-telescope?
Real time? You can’t even see the moon in real time.
Nothing has ever been seen in 'real time'.
1) Photons bounce off or are transmitted through an object.
2) They travel through space and impinge on an eye. This takes time. For example the light we see coming from the Sun left it about 8 minutes before we see it.
3) It takes some amount of time for the effects of the photons impinging on our eyes for our minds to turn that into a recognizable image. So even if the object was right up against the eye, it would still take some time for us to recognize the object. That time might be in the milliseconds or nanoseconds, but that's a huge amount of time depending on one's perspective, e.g. the lifetime of some radioactive particles, the number of calculations performed by a supercomputer, etc.
So everything we experience happened in the past. Saying that an observation that happened a few seconds ago is a different kind of observation than one that happened a hundred years ago is a mistake.
We may often find that relatively recent observations are more trustworthy than those in the distant past, but this is not always the case.
There are magicians, optical illusions, etc. that can lead us to incorrect conclusions even though they are happening right before our eyes. Conversely, we all know that Abraham Lincoln was the U. S. President when we entered the Civil War even though it happened over a hundred years ago.
They sent a very large projectile, straight at us, and it is getting closer....
