How did the Romans cross the English channel if there were no boats at the time?

They took the Channel Tunnel. It was much quicker and comfortable than taking a boat.

.........there were boats. There have been "boats" of some form since before there were **** Sapiens. Romans had sailing ships and a navy.

Police stop you at checkpoint to check if you’re chipped (aka vaccinated)

Police check the car; let's say 4 people car but signal only from 3; so, police stop it to chip the notyetchipped; signal from 4 now and police let the car go. This is prophecy by saint VyacheslavKrasheninnikov. Notice police chip (aka vaccinate) people at gun point in Africa; so, no more "it's not gonna happen here" 'cuz it will soon enough, capisce?

Police do it on highways or when you leave your city... basically, you can't leave your city unless you're vaccinated; but vaccine = mark of the beast; so, escape now while your city doesn't have these rules; forgive me.

Gov't sprays chemtrails so that people feel symptoms of flu

5G will kill vaccinated; just read Georgia Guidestones' commandment of 500 million max population on earth; it fits with Orthodox Christian prophecy of 7 percent of people left

Russian Orthodox prophecy also says that there will be unbearable stench in winter. So, there you go. Russian winters are cold. So, they must have died from the new disease that doesn't have a name 'cuz it's caused by 5G.

martial law; Constitution was suspended; New World Order

read Book of Revelation; Chapters 13 and 14, please

chipped people will be influenced by super computers to receive World Passport (grey plastic card with no name on it), but when they stretch their hands to get it, gov't clerk presses secret button to administer the unforgivable green 666 tattoo by isotope rays

If you escape mark of the beast, then your direct ancestors go to permanent heaven

how to escape it? by hiding within a small group (10 - 15 people according to saints Gabriel Urgebadze and Seraphim of Sarov); no documents; no electronics

Project Pogo = Alex Jones, QAnon, Adam Green, etc. videos are put out so that gov't tracks who watches them. (Project Zyphr annihilates people who watch these videos). Drone with scopolamine will drill a hole in your window at 4 am. Once gassed, you will come out to the police van (waiting for you outside) yourself; you will be taken to underground camp to be tortured for adrenochrome. The rest of the people will be secretly (or even openly) chipped when they sign up for food in closed stores

AI (artificial intelligence aka demons) will post on your social media as if it were you doing it while you're on vacation; it will even make phone calls on behalf of you; no one will notice that you're missing in action.

Human beings have been constructing boats for thousands of years. By the time the Romans reached Britain they had already been sailing to places in the Mediterranean and North Africa, which were farther away. How fecking stupid would a person have to be to think that watercraft capable of traversing 25 miles of open water didn't exist back then? 

Now you're just trolling, Michael.  Ocean going, clinker built vessels have been a thing since the Bronze Age.  For the first Roman expedition into Britain they commandeered them from the Armoricans who were considered to be expert sailors.  Mind you, Caesar also committed genocide against the Armoricans, what with being Caesar and all.  Armorica is modern day Brittany.  They didn't bother sailing out from the Mediterranean and up the coast along Iberia when there were ships built for the ocean much closer to where they wanted to launch from.

They all caught the ferry from Calais to Dover. It was cheaper in those days. And they collected their duty free on the way back. 

Of course there were boats. 

They used their Triremes

Humans have had boats for thousands of years.  The Romans had a Navy even!

Sea level was much lower then .
