Alien invasion message

Hello fellow humans,

This is a message to all of you. Your planet will be invaded on 25th of September in the year 2023. We have been planning this invasion ever since we have discovered your planet in year 1929. We come from planet EX3003 and we do not come in peace, so what you need to do is put your guns down and give up. Our technology is far more advanced than yours and we can easily disable your arms. We have been investigating your planet for decades and know a lot about your behaviour and weaknesses.

In year 2020 we have introduced COVID-19 and we have infected your planet with this disease so that we can track human behaviour and more closely observe your bodily functions. We have done enough research and our investigation is now complete. We will land on a country called Ireland on 25th of September 2023 and we will occupy a city which Irish people call Dublin. There is no point to resist. Our lasers can drill through tough material and our technology allows us to disable all electronic equipment within 100km radius.

Goodbye.

Covid-19 was first detected in 2019 - you couldn't have introduced it in 2020.

They probably used a tardis to go back in time and frame the chinese government
