Speaking in tongues

I have often heard and witnessed people speaking in tongues.  However as I scour the internet and other blogs I often see where people have written in tongues.  Is this possible?  Where in scripture does it indicate that tongues can be written and read by us?

If you have any thoughts or answers please let me know.  I have never seen where anyone has been able to write and read in tongues.  Was English even a language in Biblical days?  If not then how can we transcribe this Spiritual gift into everyday letters, sounds and words?  There is scripture in Acts that says that when they spoke in tongues all in each language represented there all understood in their own language.  There is also passage in Corinthians where Paul speaks of the gifts of the Spirit but each time that I have seen it mentioned in the Bible it has been spoken not written.  thoughts?

Looking forward to getting your responses.

Be Blessed,

Acts 2:1-13

¹When the day of Pentecost had come, they were all together in one place. ²And suddenly from heaven there came a sound like the rush of a violent wind, and it filled the entire house where they were sitting. ³Divided tongues, as of fire, appeared among them, and a tongue rested on each of them. ⁴All of them were filled with the Holy Spirit and began to speak in other languages, as the Spirit gave them ability. ⁵Now there were devout Jews from every nation under heaven living in Jerusalem. ⁶And at this sound the crowd gathered and was bewildered, because each one heard them speaking in the native language of each. ⁷Amazed and astonished, they asked, “Are not all these who are speaking Galileans? ⁸And how is it that we hear, each of us, in our own native language? ⁹Parthians, Medes, Elamites, and residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia, ¹⁰Phrygia and Pamphylia, Egypt and the parts of Libya belonging to Cyrene, and visitors from Rome, both Jews and proselytes, ¹¹Cretans and Arabs–in our own languages we hear them speaking about God’s deeds of power.” ¹²All were amazed and perplexed, saying to one another, “What does this mean?” ¹³But others sneered and said, “They are filled with new wine.”

1 Corinthians 12:6-11

⁶and there are varieties of activities, but it is the same God who activates all of them in everyone. ⁷To each is given the manifestation of the Spirit for the common good. ⁸To one is given through the Spirit the utterance of wisdom, and to another the utterance of knowledge according to the same Spirit, ⁹to another faith by the same Spirit, to another gifts of healing by the one Spirit, ¹⁰to another the working of miracles, to another prophecy, to another the discernment of spirits, to another various kinds of tongues, to another the interpretation of tongues. ¹¹All these are activated by one and the same Spirit, who allots to each one individually just as the Spirit chooses.

1 Corinthians 14:2-5

²For those who speak in a tongue do not speak to other people but to God; for nobody understands them, since they are speaking mysteries in the Spirit. ³On the other hand, those who prophesy speak to other people for their upbuilding and encouragement and consolation. ⁴Those who speak in a tongue build up themselves, but those who prophesy build up the church. ⁵Now I would like all of you to speak in tongues, but even more to prophesy. One who prophesies is greater than one who speaks in tongues, unless someone interprets, so that the church may be built up.
